A by-product of the destructive distillation of coal used as a topical antieczematic. It is an antipruritic and keratoplastic agent used also in the treatment of psoriasis and other skin conditions. Occupational exposure to soots, tars, and certain mineral oils is known to be carcinogenic according to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985) (Merck Index, 11th ed).
A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population.

An ancient country in western Asia, by the twentieth century divided among the former USSR, Turkey, and Iran. It was attacked at various times from before the 7th century B.C. to 69 B.C. by Assyrians, Medes, Persians, the Greeks under Alexander, and the Romans. It changed hands frequently in wars between Neo-Persian and Roman Empires from the 3d to 7th centuries and later under Arabs, Seljuks, Byzantines, and Mongols. In the 19th century Armenian nationalism arose but suffered during Russo-Turkish hostilities. It became part of the Soviet Republic in 1921, with part remaining under Turkey.

Mechanisms and mediators in coal dust induced toxicity: a review. (1/268)Chronic inhalation of coal dust can cause several lung disorders, including simple coal workers pneumoconiosis (CWP), progressive massive fibrosis (PMF), chronic bronchitis, lung function loss, and emphysema. This review focuses on the cellular actions and interactions of key inflammatory cells and target cells in coal dust toxicity and related lung disorders, i.e. macrophages and neutrophils, epithelial cells, and fibroblasts. Factors released from or affecting these cells are outlined in separate sections, i.e. (1) reactive oxygen species (ROS) and related antioxidant protection mechanisms, and (2) cytokines, growth factors and related proteins. Furthermore, (3) components of the extracellular matrix (ECM), including the modifying role of ROS, cytokines, proteases and antiproteases are discussed in relation to tissue damage and remodelling in the respiratory tract. It is recognised that inhaled coal dust particles are important non-cellular and cellular sources of ROS in the lung, and may be significantly involved in the damage of lung target cells as well as important macromolecules including alpha-1-antitrypsin and DNA. In vitro and in vivo studies with coal dusts showed the up-regulation of important leukocyte recruiting factors, e.g. Leukotriene-B4 (LTB4), Platelet Derived Growth Factor (PDGF), Monocyte Chemotactic Protein-1 (MCP-1), and Tumor Necrosis Factor-alpha (TNF alpha), as well as the neutrophil adhesion factor Intercellular Adhesion Molecule-1 (ICAM-1). Coal dust particles are also known to stimulate the (macrophage) production of various factors with potential capacity to modulate lung cells and/or extracellular matrix, including O2-., H2O2, and NO, fibroblast chemoattractants (e.g. Transforming Growth Factor-beta (TGF beta), PDGF, and fibronectin) and a number of factors that have been shown to stimulate and/or inhibit fibroblast growth or collagen production such as (TNF alpha, TGF beta, PDGF, Insulin Like Growth Factor, and Prostaglandin-E2). Further studies are needed to clarify the in vivo kinetics and relative impact of these factors. (+info)
Health impacts of domestic coal use in China. (2/268)Domestic coal combustion has had profound adverse effects on the health of millions of people worldwide. In China alone several hundred million people commonly burn raw coal in unvented stoves that permeate their homes with high levels of toxic metals and organic compounds. At least 3,000 people in Guizhou Province in southwest China are suffering from severe arsenic poisoning. The primary source of the arsenic appears to be consumption of chili peppers dried over fires fueled with high-arsenic coal. Coal samples in the region were found to contain up to 35,000 ppm arsenic. Chili peppers dried over high-arsenic coal fires adsorb 500 ppm arsenic on average. More than 10 million people in Guizhou Province and surrounding areas suffer from dental and skeletal fluorosis. The excess fluorine is caused by eating corn dried over burning briquettes made from high-fluorine coals and high-fluorine clay binders. Polycyclic aromatic hydrocarbons formed during coal combustion are believed to cause or contribute to the high incidence of esophageal and lung cancers in parts of China. Domestic coal combustion also has caused selenium poisoning and possibly mercury poisoning. Better knowledge of coal quality parameters may help to reduce some of these health problems. For example, information on concentrations and distributions of potentially toxic elements in coal may help delineate areas of a coal deposit to be avoided. Information on the modes of occurrence of these elements and the textural relations of the minerals and macerals in coal may help predict the behavior of the potentially toxic components during coal combustion.

Molecular epidemiological study of non-small-cell lung cancer from an environmentally polluted region of Poland. (3/268)The p53 mutation spectrum can generate hypotheses linking carcinogen exposure to human cancer. Although it is well-documented that tobacco smoking is a major cause of lung cancer, the contribution of air pollution is less well-established. We determined the molecular and immunohistochemical changes (p53 gene mutations, p53 protein accumulation and WAF1 protein expression) and genetic polymorphisms of GSTM1, CYP1A1 and CYP2D6 genes in a case series of non-small-cell lung cancers from Silesia. This region of southern Poland is highly industrialized with considerable environmental pollution. More than 50% of lung cancers (90/164) contained p53 mutations and 75% showed the combined alteration of the p53 gene and protein accumulation. Males occupationally exposed to coal-derived substances showed a relatively high frequency of squamous and large-cell carcinomas, relatively frequent mutations in codon 298 of p53 and a low frequency of p53 immunohistochemically positive tumours. Codon 298 GAG-->TAG mutations have rarely been found in lung cancers in other populations. We found no correlation between WAF1 protein expression and mutations in the p53 gene or p53 protein accumulation. No statistically significant relationship was found between p53 mutations and GSTM1, CYP1A1, CYP2D6 genotypes. Never smokers with lung cancers from Silesia had a higher frequency of G:C-->T:A transversions than previously reported of the p53 mutation spectrum in never smokers (6/15 vs 4/34; P = 0.06 by chi2). These data are a tentative indication that occupational and environmental exposure to polycyclic aromatic hydrocarbons, such as benzo(a)pyrene, in polluted air contributes to the molecular pathogenesis of lung cancer in never smokers.

Modulating influence of cytochrome P-450 MspI polymorphism on serum liver function profiles in coke oven workers. (4/268)OBJECTIVES: It was reported previously that topside oven workers with heavy exposure to coke oven emissions had increased serum activities of hepatic aminotransferase in one coke oven plant. This study was conducted to investigate the modifying effect of CYP1A1 MspI polymorphism on liver function profiles in coke oven workers. METHODS: 88 coke oven workers from a large steel company in Taiwan were studied in 1995-6. Exposure was categorised by work area: topside oven workers and sideoven workers. Liver function profiles including serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), r-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and total bilirubin (BIL) were examined in the morning after personal exposure measurements. The MspI polymorphism was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). RESULTS: Five of 23 (22%) topside oven workers and seven of 65 (11%) sideoven workers had the CYP1A1 MspI homozygous variant genotype. With sideoven workers with the combined wild type and heterozygous variant as the reference group in multiple regression models, it was found that topside oven workers with the combined traits had mean AST and ALT activities that were 21% and 46% higher (95% confidence interval (95% CI) 4% to 42% and 12% to 91%, respectively) than the reference group after adjusting for appropriate confounders. Also, topside oven workers with the homozygous variant trait had mean AST, ALT, and GGT activities that were 59%, 68%, and 157% higher (95% CI 21% to 109%, 6% to 168%, and 39% to 374%, respectively) than the reference group. The prevalence of an abnormal hepatocellular pattern (AST > 37 IU/l or ALT > 39 IU/l) was more common in the topside oven workers with the homozygous variant than in the sideoven workers with the other combined genotypes (adjusted odds ratio 9.9, 95% CI 1.2 to 82.3) after adjusting for appropriate confounders. CONCLUSIONS: The CYP1A1 MspI polymorphism may modify the biotransformation of coke oven emissions, which results in hepatocellular damage in coke oven workers. (+info)
Indoor air pollution in developing countries and acute lower respiratory infections in children. (5/268)BACKGROUND: A critical review was conducted of the quantitative literature linking indoor air pollution from household use of biomass fuels with acute respiratory infections in young children, which is focused on, but not confined to, acute lower respiratory infection and pneumonia in children under two years in less developed countries. Biomass in the form of wood, crop residues, and animal dung is used in more than two fifths of the world's households as the principal fuel. METHODS: Medline and other electronic databases were used, but it was also necessary to secure literature from colleagues in less developed countries where not all publications are yet internationally indexed. RESULTS: The studies of indoor air pollution from household biomass fuels are reasonably consistent and, as a group, show a strong significant increase in risk for exposed young children compared with those living in households using cleaner fuels or being otherwise less exposed. Not all studies were able to adjust for confounders, but most of those that did so found that strong and significant risks remained. CONCLUSIONS: It seems that the relative risks are likely to be significant for the exposures considered here. Since acute lower respiratory infection is the chief cause of death in children in less developed countries, and exacts a larger burden of disease than any other disease category for the world population, even small additional risks due to such a ubiquitous exposure as air pollution have important public health implications. In the case of indoor air pollution in households using biomass fuels, the risks also seem to be fairly strong, presumably because of the high daily concentrations of pollutants found in such settings and the large amount of time young children spend with their mothers doing household cooking. Given the large vulnerable populations at risk, there is an urgent need to conduct randomised trials to increase confidence in the cause-effect relationship, to quantify the risk more precisely, to determine the degree of reduction in exposure required to significantly improve health, and to establish the effectiveness of interventions.

Indoor coal combustion emissions, GSTM1 and GSTT1 genotypes, and lung cancer risk: a case-control study in Xuan Wei, China. (6/268)The lung cancer mortality rate in Xuan Wei County, China is among the highest in the country and has been associated with exposure to indoor smoky coal emissions that contain high levels of polycyclic aromatic hydrocarbons. This risk may be modified by variation in metabolism genes, including GSTM1, which encodes an enzyme known to detoxify polycyclic aromatic hydrocarbons. To investigate the relationship between GST genotypes and lung cancer risk in Xuan Wei County, we analyzed GSTM1 and GSTT1 genotypes in a population-based case-control study. A total of 122 lung cancer patients and 122 controls, individually matched by age, sex, and home fuel type, were studied. Compared to subjects who used less than 130 tons of smoky coal during their lifetime, heavier users (> or =130 tons) had a 2.4-fold (95% confidence interval, 1.3-4.4) increased risk of lung cancer. The GSTM1-null genotype was associated with a 2.3-fold (95% confidence interval, 1.3-4.2) increased risk of lung cancer. Furthermore, there was some evidence that smoky coal use was more strongly associated with lung cancer risk among GSTM1-null versus GSTM1-positive individuals. In contrast, the GSTT1 genotype was not significantly associated with lung cancer risk. Our data suggest that the GSTM1-null genotype may enhance susceptibility to air pollution from indoor coal combustion emissions. (+info)
Silicosis and coal workers' pneumoconiosis. (7/268)Exposure to coal mine dust and/or crystalline silica results in pneumoconiosis with initiation and progression of pulmonary fibrosis. This review presents characteristics of simple and complicated coal workers' pneumoconiosis (CWP) as well as pathologic indices of acute and chronic silicosis by summarizing results of in vitro, animal, and human investigations. These results support four basic mechanisms in the etiology of CWP and silicosis: a) direct cytotoxicity of coal dust or silica, resulting in lung cell damage, release of lipases and proteases, and eventual lung scarring; b) activation of oxidant production by pulmonary phagocytes, which overwhelms the antioxidant defenses and leads to lipid peroxidation, protein nitrosation, cell injury, and lung scarring; c) activation of mediator release from alveolar macrophages and epithelial cells, which leads to recruitment of polymorphonuclear leukocytes and macrophages, resulting in the production of proinflammatory cytokines and reactive species and in further lung injury and scarring; d) secretion of growth factors from alveolar macrophages and epithelial cells, stimulating fibroblast proliferation and eventual scarring. Results of in vitro and animal studies provide a basis for proposing these mechanisms for the initiation and progression of pneumoconiosis. Data obtained from exposed workers lend support to these mechanisms. (+info)
Laryngeal and hypopharyngeal cancers and occupational exposure to formaldehyde and various dusts: a case-control study in France. (8/268)OBJECTIVES: A case-control study was conducted in France to assess possible associations between occupational exposures and squamous cell carcinomas of the larynx and hypopharynx. METHODS: The study was restricted to men, and included 201 hypopharyngeal cancers, 296 laryngeal cancers, and 296 controls (patients with other tumour sites). Detailed information on smoking, alcohol consumption, and lifetime occupational history was collected. Occupational exposure to seven substances (formaldehyde, leather dust, wood dust, flour dust, coal dust, silica dust, and textile dust) was assessed with a job exposure matrix. Exposure variables used in the analysis were probability, duration, and cumulative level of exposure. Odds ratios (ORs) with their 95% confidence intervals (95% CIs) were estimated by unconditional logistic regression, and were adjusted for major confounding factors (age, smoking, alcohol, and when relevant other occupational exposures). RESULTS: Hypopharyngeal cancer was found to be associated with exposure to coal dust (OR 2.31, 95% CI 1.21 to 4.40), with a significant rise in risk with probability (p<0.005 for trend) and level (p<0.007 for trend) of exposure. Exposure to coal dust was also associated with an increased risk of laryngeal cancer (OR 1.67, 95% CI 0.92 to 3.02), but no dose-response pattern was found. A significant relation, limited to hypopharyngeal cancer, was found with the probability of exposure to formaldehyde (p<0.005 for trend), with a fourfold risk for the highest category (OR 3.78, 95% CI 1.50 to 9.49). When subjects exposed to formaldehyde with a low probability were excluded, the risk also increased with duration (p<0.04) and cumulative level of exposure (p<0.14). No significant association was found for any other substance. CONCLUSION: These results indicate that exposure to formaldehyde and coal dust may increase the risk of hypopharyngeal cancer. (+info)

Report Ties Coal Plants to Chinas Water Shortage | China Digital Times (CDT)
Chinas coal-fired power plants consume more water where water is scarce than plants in any other country, according to the report, which assessed global water depletion from coal use.. [...] Greenpeace said the continuing burning of coal for power plants and factories in northern China, along with the growth of the coal-to-chemicals industry, is exacerbating the water crisis. In much of northern China, people are using water faster than it can be regenerated, Greenpeace said, posing a serious threat to local ecology.. At the end of 2013, China had 45 percent of the worlds coal-fired power plants, with a total installed capacity of 358 gigawatts, according to a summary of findings in the 60-page report, The Great Water Grab. Nearly half of the plants were in water-scarce areas, and those had a total annual water consumption of 3.4 billion cubic meters, enough to meet the basic needs of about 186 million people, the researchers found.. [...] Across all of China, coal-fired power plants ...
New Coal Revolution May Change Everything - The Global Warming Policy Forum (GWPF)
Coal is much cheaper than other fossil fuels. Compared with liquefied natural gas and oil, it is priced roughly half and one-third per caloric unit, respectively.. The cost of building a CoolGen plant is estimated to be about 20% higher than that for conventional coal-fired plants. But it will be economically more advantageous than plants using LNG or oil for power generation as long as the price gaps continue.. In addition, a CoolGen plant can use low-quality coal, which is cheaper than standard coal, because it gasifies the fuel.. Existing coal-fired power plants are estimated to emit twice as much CO2 as standard LNG-based plants. Although coal is cheaper, the construction of conventional coal-fired plants is prohibited in principle in Japan for the sake of curbing CO2 emissions.. But the situation is different overseas. The International Energy Agency forecasts that coal-fired power plants in the world will generate a total of 2.4 billion kilowatts in 2040, up from nearly 1.9 billion in ...
Anthracite - Wikipedia
Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation. Anthracite differs from ordinary bituminous coal by its greater hardness (2.75-3 on the Mohs scale), its higher relative density of 1.3-1.4, and luster, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter. It is also free from included soft or fibrous notches and does not soil the fingers when rubbed. Anthracitization is the transformation of bituminous coal into anthracite. The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis. The heat content of anthracite coal consumed in the United States averages 25 million Btu/ton (29 MJ/kg), on the as-received basis (i.e., containing both inherent moisture and mineral matter). Since the 1980s, ...
Investigation of local mercury deposition from a coal-fired power plant using mercury isotopes. - Semantic Scholar
Coal combustion accounts for approximately two-thirds of global anthropogenic mercury (Hg) emissions. Enhanced deposition of Hg can occur close to coal-fired utility boilers (CFUBs), but it is difficult to link specific point sources with local deposition. Measurement of Hg stable isotope ratios in precipitation holds promise as a tool to assist in the identification of local Hg deposition related to anthropogenic emissions. We collected daily event precipitation samples in close proximity to a large CFUB in Crystal River, Florida. Precipitation samples collected in Crystal River were isotopically distinct and displayed large negative δ(202)Hg values (mean = -2.56‰, 1 SD = 1.10‰, n = 28). In contrast, precipitation samples collected at other sites in FL that were not greatly impacted by local coal combustion were characterized by δ(202)Hg values close to 0‰ (mean = 0.07‰, 1 SD = 0.17‰, n = 13). These results indicate that, depending on factors such as powdered coal isotopic composition and

Health Effects of Subchronic Inhalation of Simulated Downwind Coal Combustion Emissions - Digital Library
The purpose of this project was to conduct a comprehensive laboratory-based evaluation of selected respiratory and cardiac health hazards of subchronic (up to 6 months) inhalation of simulated key components of downwind plume emissions of coal combustion. This project was performed as an integral part of a joint government-industry program termed the National Environmental Respiratory Center (NERC), which is aimed at disentangling the roles of different physical-chemical air pollutants and their sources in the health effects associated statistically with air pollution. The characterization of the exposure atmosphere and the health assays were identical to those employed in the NERC protocols used to evaluate other pollution source emissions, such as diesel, gasoline, and wood combustion. The project had two phases, each encompassing multiple tasks. Guidelines for the composition of the exposure atmosphere were set by consensus of an expert workshop. Development of the capability to generate the
Whats the Real Story With Clean Coal?
The goal of the Sierra Clubs Beyond Coal campaign is to retire one-third of the nations over 500 coal plants by 2020; so far 147 have retired. Burning coal, the dirtiest fossil fuel, still produces about 40 percent of the electricity in the U.S., although this figure has been declining because of the natural gas boom. Coal mining destroys mountaintops and dumps rubble and toxic waste into streams. Burning coal is responsible for soot and smog that result in over $100 billion in health costs each year. Coal plants release toxic mercury into the air and leave behind dangerous coal ash pollution.. Moreover, coal-fired power plants are responsible for one third of all U.S. carbon dioxide emissions each year. Carbon dioxide, a powerful greenhouse gas, traps heat and warms the planet. In May, carbon emissions in the atmosphere topped 400 parts per million for the first time in over 2.5 million years. Humans have now put enough carbon dioxide into the atmosphere to change life on Earth as we know it; ...
Too late for Oregons coal terminal: Exporting US coal to Asia could drop emissions 21 percent | Watts Up With That?
From Duke University. Superior energy efficiency of South Korean plants, and choice of replacement fuels in US, are key to success. DURHAM, N.C. - Under the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the United States, according to a new Duke University-led study.. Despite the large amount of emissions produced by shipping the coal such a long distance, our analysis shows that the total emissions would drop because of the superior energy efficiency of South Koreas newer coal-fired power plants, said Dalia Patiño-Echeverri, assistant professor of energy systems and public policy at Duke.. For the reduction to occur, U.S. plants would need to replace the exported coal with natural gas. And in South Korea, the imported coal must replace other coal as the power source. However, if imported U.S. coal were to replace natural gas or nuclear generation in Korea, the ...

While lung cancer risk has been linked to the household use of bituminous coal, no study has comprehensively evaluated the risk of lung cancer associated with the mining of this coal in Xuanwei. In Xuanwei, coal is typically extracted from underground mines, without ventilation, and transported to the surface using carts powered by manpower or electricity. Methods: We evaluated the risk of lung cancer and working as a coal miner, in the absence of diesel exhaust exposure, in a population-based case-control study of 260 male lung cancer cases and 260 age-matched male controls with ...
How Did Coal Seams Form? | The Institute for Creation Research
When I drive from Dallas to Colorado, I sometimes see southbound trains loaded with coal from vast reserves buried in Wyoming rock layers. This coal helps power the homes and industries of the almost eight million folks in the Dallas-Fort Worth metroplex.1 How did all that coal get buried there?. For a society that uses so much coal, we seem to know very little about its origins. Truth be told, coal formation holds mysteries. We cant travel back in time to see what happened, but we can do experiments and follow clues that refine our ideas.. What clues does the standard story offer? Peat has played too big a role when it comes to explaining coal. According to the United States Geological Survey, Peat is the precursor to coal.2 How do they know? Peat does not form coal today. Peat bogs and coal beds both contain bits of wood, but they have many other differences.. For example, peat bogs are riddled with roots. Coal seams show none.3 Todays peat bogs dont extend across state-size areas like ...
Coal Ash Sites Posing Increasing Dangers To Water Supplies, Public Health | DeSmogBlog
The Environmental Integrity Project (EIP) has once again put together a fantastic report regarding water contamination near coal ash disposal sites. Last year, the EIP released several reports showing that drinking water near coal ash disposal sites in states across America contained dangerous levels of heavy metals and other toxins, including arsenic. In total, last years report revealed 53 sites in the United States where coal ash had polluted drinking water supplies. The new report has identified a total of 116 coal ash sites in America that are leaching deadly toxins into the environment. The new EIP report resulted from a Freedom of Information Act (FOIA) request to the EPA, which revealed that 49 different coal-fired power plants acknowledged that their own testing showed that groundwater pollution around their disposal sites far exceeded the federally acceptable levels. Among the chemicals reported to exceed federal standards at the coal-fired plants disposal sites are:

Coal in Australia - Wikipedia
In 2008/09, 487 million tonnes of coal was mined, and 261 million tonnes was exported. In 2009, Australia was the fourth-highest coal producer in the world, producing 335 megatonnes (Mt) of anthracite and 64 Mt of lignite. Australia was the biggest anthracite exporter, with 31% of global exports (262 Mt out of 836 Mt total). 78% of 2009 anthracite production was exported (262 Mt out of 335 Mt total). Australias global anthracite export share was 14% of all production (836 Mt out of 5,990 Mt total). In 2011, coal exports were Australias second-largest source of export income, after iron ore exports. In 2011, coal exports were worth A$47 billion Australian dollars, or US$47.8 billion, with US$15.6 billion coming from exports of thermal coal for power stations.

Minerals | Free Full-Text | Distribution, Enrichment and Modes of Occurrence of Arsenic in Chinese Coals
Arsenic is one of the toxic trace elements in coals, which is harmful to both the ecological environment and human health. Based on published literature and the data obtained by our research group, a total of 5314 As concentrations of Chinese coals were analyzed. The arithmetic mean of arsenic content in Chinese coals is 6.97 mg/kg. Choosing the percentage of provincial coal resources in national coal resources as the weighting factor, the weighted average of arsenic content in Chinese coals is 5.33 mg/kg. The content of arsenic in Chinese coals increases from the north to the south. High arsenic content in coal primarily occurs in southwestern Yunnan and certain coalfields in the Guizhou Province. Additionally, arsenic is enriched in the coals from some regions, i.e., the western Yunnan, Guangxi, Tibet, southwestern Liaoning, Jilin, and Henan. The arsenic content in coals of different coal-forming periods shows an overall regularity: Paleogene and Neogene > Late Triassic > Late Permian > Late

Minerals | Free Full-Text | Coupling Effect of Intruding Water and Inherent Gas on Coal Strength Based on the Improved (Mohr...
When employing hydraulic processes to increase gas drainage efficiency in underground coal mines, coal seams become a three-phase medium, containing water intruding into the coal pores with the inherent occurrence of gas. This can change the stress state of the coal and cause instability. This work studied the mechanical properties of coal containing water and gas and derived an appropriate failure criterion. Based on mixture theory of unsaturated porous media, the effective stress of coal, considering the interaction of water and gas, was analyzed, and the failure criterion established by combining this with the Mohr-Coulomb criterion. By introducing the stress factor of matrix suction and using fitted curves of experimentally determined matrix suction and moisture content, the relationships between coal strength, gas pressure, and moisture content were determined. To verify the established strength theory, a series of triaxial compression strength tests of coal containing water and gas were carried

Is Clean Coal Doable? Both Clinton and Trump Would Give it a Try - Environmental Leader
The second to the last question during the presidential debate on Sunday night was about energy and how the candidates policies would influence the nations direction. With that, Donald Trump referenced clean coal, noting that theres enough coal to last 1,000 years. Lets examine that.. What is clean coal and is it technically feasible? Coal-fired power plants contribute a third of all man-made carbon emissions in the United States. The goal, though, is to gasify the coal and separate the carbon - before capturing and burying it. While such technologies have been demonstrated, they have yet to have much commercial appeal.. The United States, in fact, is investing $8 billion into the effort. But it has also pulled out of some high profile projects, given that the time tables and budgets keep getting stretched. And the Obama administration has said that it will continue to finance the effort, generally speaking, although it is harder argument to make now that natural gas prices are so ...

Fly Ash, Air Pollution in Uttar PradeshIndia | Panki Katra Fly Ash Contamination
Coal is India s most abundant resource, and it will continue to play a pivotal role in the country over the upcoming decades. There currently exist in India 82 coal-fired power plants, each of which uses around 1,000 tons of coal and produces about 13.34 tons of fly ash. Fly ash is, alone, a waste product and its responsible disposal poses a huge problem. From each power station, thousands of tons of fly ash are pumped into the ash ponds in the form of slurry (fly ash mixed with water) every day; these lagoons occupy millions of acres of agricultural land all over India. When coal is burned in a plant, two types of ash are produced: fly ash and bottom ash. Fly ash, otherwise known as pulverized fuel ash, is the residue of coal combustion and is comprised of very fine, powerdy glass-like particles. Because it is so fine, it is highly susceptible to wind erosion; its light color grayish white reflects more light than dirt, raising surface temperature. Bottom ash refers to the non
End Coal | Is India starting to waver on coal?
Bob Burton. Seemingly unrelated events in the last few weeks suggest that coals role in Indias future may be far more tenuous than widely portrayed.. From court rulings over pollution, to private power companies dumping coal projects in favour of solar, to Coal India revealing it doesnt know what to do about huge stockpiles of unwanted coal, Indias energy policy is in a state of flux.. Clearing the air. Just as public revulsion over air and water pollution has driven a dramatic shift in energy policy in China, it is increasingly coming to the fore in India too. While pollution from cars and burning rubbish are significant contributors, coal is coming in for its fair share of attention.. Late last week the Goa State Pollution Control Board, after reviewing data which showed air pollution at up to double permitted levels, directed subsidiaries of Adani and JSW to cut coal imports by 25 per cent through their facilities at Mormugao Port.. They also imposed a set of other conditions to cut coal ...
Difference between revisions of Coal - Ohio History Central
The first European settlers in Ohio recognized the presence of coal in natural outcrops in stream and river banks in the eastern part of the state. As the industrial revolution began, Ohio�s coal resources became increasingly important. One of the primary objectives of the first Geological Survey of Ohio in 1837-1838 was to survey the mineral resources of the state, particularly coal. Soon, coal was being mined as a fuel to heat homes and businesses. Development of the Ohio canal system in the 1830�s and 1840�s permitted easy transport of coal from mines to markets. By the mid 1800�s, railroads began to replace the canals, allowing for faster and more efficient delivery of coal to consumers. By the late 1800�s, mechanization and improvement of mining methods led to a steady increase in the production of Ohio coal. Much coal was used to make coke to fuel the many steel mills that dotted the upper Ohio River valley. Eventually, coal became the primary source of energy to generate ...

Why Phasing Out Coal in Alberta Isnt As Hard As They Say
Ontario had exactly the same amount of absolute megawatts derived from coal as we do now and their last plant closes this year. Its a tiny little plant. Its in Thunder Bay which only has 300 megawatts and its the last one to close and theyll have no more coal-fired power in that province.. And Ontario did it fast, it took them just over a decade and now they are practically off coal altogether. They kept the lights on and also integrated massive amounts of solar, wind and biomass into their grid. Nova Scotia is trending in that direction as well. For a place that has so heavily depended on coal-fired power for so long coal is now down to 59 per cent of the electricity mix and provincial law mandates that renewables be 25 per cent of the electricity mix by 2015.. At the event was Donna Kennedy-Glans, a Progressive Conservative MLA and recently appointed associate minister of a brand new portfolio - Electricity and Renewable Energy..

Coal mining - Wikipedia
Coal was mined in America in the early 18th century, and commercial mining started around 1730 in Midlothian, Virginia.. The American share of world coal production remained steady at about 20 percent from 1980 to 2005, at about 1 billion short tons per year. The United States was ranked as the second highest coal producing country in the world in 2010, and possesses the largest coal reserves in the world. In 2008 then-President George W. Bush stated that coal was the most reliable source of electricity. However, in 2011 President Barack Obama said that the US should rely more on clean sources of energy that emit lower or no carbon dioxide pollution. For a time, while domestic coal consumption for electric power was being displaced by natural gas, exports were increasing. US net coal exports increased ninefold from 2006 to 2012, peaked at 117 million short tons in 2012, then declined to 63 million tons in 2015. In 2015, 60% of net US exports went to Europe, 27% to Asia.US coal ...

Thirst for power: improving water efficiency in coal-fired power plants - Power Technology
Like most other steam-producing electricity plants, coal units typically withdraw and consume water from nearby water bodies such as lakes, rivers or oceans, to create steam for turning their turbines.. The Union of Concerned Scientists (UCS) reports that a typical coal-fired power plant employing a once-through cooling system withdraws 70−180 billion gallons of water every year and consumes 0.36-1.1 billion gallons of it. A coal plant with a wet-recirculating cooling system extracts only a fraction of that figure, but still consumes 1.7−4.0 billion gallons a year, while a dry-cooled system uses much less.. Around 53% of US coal plants use once-through cooling and 40% wet-recirculating systems. The US Environmental Protection Agency (EPA) estimates that dry-cooling facilities produce around 7% less power than wet-recirculating plants; hence, under 1% of units use this technology.. Water also plays a pivotal role in coal mining and transportation. In addition to burying streams, contaminating ...
coal-fired power plants | Fraser Institute
In 2005, the province of Ontario began a process that would eventually lead to the phasing out of its coal-fired power plants, the largest of which were the Lambton and Nanticoke facilities in southern Ontario. The rationale for shuttering these plants was a 2005 cost-benefit analysis that assumed that about $3 billion in annual savings to the health care system would come from the reduction of smog-related air contaminants. However, that analysis, and another one done for the province the same year on the effects of cross-border air pollution, reported that the phase-out of coal would have only very modest effects on Ontario air quality, which is consistent with emissions inventory data showing that electric power generation was a minor contributor to particulate and ozone pollution at the time. The cost savings estimate came from assuming very large health effects associated with very small changes in air pollution.. In the aftermath of the coal phase-out, and the extremely costly changes to ...

Surface Composition of Respirable Silica Particles in a Set of U.S. An by J. C. Harrison, P. S. Brower et al.
Respirable particles of high-percentage silica content from anthracite and bituminous coal mine dust samples were analyzed for aluminosilicate clay surface coating, by measuring silicon and aluminum X-ray spectra using scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDS). Silicon and aluminum elemental ratios were determined with incident electron energies of 20 and 5 keV to reveal whether surface occlusion was present. Some 20 respirable-sized, non-agglomerated particles with silicon fraction of signal of 75% or more (for elements above sodium) were analyzed for each of 12 coal mine dust samples. Mine dust samples were from U.S. anthracite and bituminous coal mining regions involved in epidemiological studies of the U.S. National Study of Coal Workers Pneumoconiosis. Some particles of high-percentage silica content exhibited a decrease in the ratio of silicon-to-aluminum K-alpha line intensities with decreasing electron beam accelerating voltage, consistent with aluminosilicate clay
Montanas Quality of Life Tied to Air Quality - New West
The Environmental Protection Agency is currently working to establish common-sense standards for pollution such as smog, particulate matter, carbon dioxide, mercury, and arsenic. The agency is gathering public comment on its Mercury and Air Toxics Rule, greenhouse gas standards are nearly finalized, and an ozone and smog rule is under development. These measures will protect public health, save millions of dollars on health care costs, improve workplace safety and productivity, and create much needed jobs.. Mercury pollution from coal-fired power plants contributes to the contamination of our fisheries and puts Montanans at risk, especially women and children. And although Montana is one of 19 states that have a standard for mercury emissions, mercury pollution does not respect state boundaries, which is why it is so important that the EPA regulate coal-fired power plants throughout the United States, because many states have not developed their own mechanisms for reduction. According to the ...
01/10/2012: EPA, State of Colorado join Childrens Hospital to highlight benefits of new mercury and air toxics standards for...
This long-awaited effort to reduce toxic air pollution from oil and coal-fired power plants means cleaner air and healthier waters for Colorado, said Jim Martin, EPAs regional administrator in Denver. The Mercury and Air Toxics Standards will protect Colorados families from harmful pollution and will generate health benefits and economic investments that far outweigh the costs of compliance. EPA estimates the new Mercury and Air Toxics Standards will prevent up to 140 premature deaths and create $1.1 billion in health benefits annually in Colorado beginning in 2016, when the rules become fully effective. Mercury has been shown to harm the nervous systems of children exposed in the womb, impairing thinking, learning and early development. Other pollutants that will be reduced by these standards can cause cancer, premature death, heart disease, and asthma. The standards will apply to generating units at a dozen coal-fired power plants in Colorado and will reinforce the States efforts to ...
Washington: TransAlta Coal-Fired Power Plant Under Fire for Mercury
Calls for TransAlta to reduce emissions grew louder last week as a Seattle-based coalition released a report detailing what it called an extremely dangerous level of mercury at the plant, about a month before the U.S. Environmental Protection Agency is expected to propose new mercury-emission requirements.. Environment Washington, a citizen-driven environmental advocacy group, held a news conference Thursday at the U.S. Environmental Protection Agencys Seattle office, in which it released findings in a report titled Dirty Energys Assault on Our Health: Mercury..

Particle sizing of coal mine dust by pattern recognition of laser diffraction | (1996) | Zhao | Publications | Spie
Particle sizing by laser diffraction provides a prospective method for real-time detection of weight and size information of coal mine dust. Quickness, accuracy and ability to measure total and respirable dust weighs are some of the basic requirements for inversion method of the coal mine dust transducer. This paper presents a quick inversion scheme that can be referred to as pattern recognition of laser diffraction field. Single-chip computer system simulation results show that this method not only furnishes excellent estimates of both total and respirable dust weights in a very short time but also features high anti- noise ability and stability ...
Coal mine rules changes to go into effect this summer, draw criticism
GRAND JUNCTION - New coal mining rules that go into effect in August are designed to decrease the hundreds of deaths that still occur from black lung disease. But the costly new rules are not popular with all miners and mine operators.. Officials from the Mine Safety and Health Administration spent more than five hours Thursday explaining the new regulations to dozens of coal mine operators and miners. The gathering in Grand Junction was the last of a series of seven meetings held around the country in states with coal mines.. We still see miners getting black lung, said Kevin Stricklan, administrator of Coal Mine Safety and Health for MSHA. Two hundred and eighty people die every year from respirable illness. Since 1968, over 76,000 miners have died.. To drop the numbers of what is medically called pneumoconiosis and to cut the $45 billion paid out in federal compensation, MSHA is instituting the first changes to coal mine dust rules since 1969..

Texaco Improves Coal Liquefaction Solvent | Research & Development | News | West Virginia Coal Association
United States Patent: 4476009. Herein we see that Texaco, prior to their acquisition by Chevron, continued to develop Coal conversion and liquefaction technologies, as per a number of our previous reports, into the 1980s.. Perhaps of interest in this example is further confirmation of the fact that primary Coal oils can be hydrogenated, through pretty standard petroleum refinery techniques, and thereby made to function as the agents of hydrogenation and liquefaction for more raw Coal.. Of special interest could be the fact that this Texaco process might represent a better way of using such Coal-derived Coal solvents, as opposed to WVUs West Virginia Process for the direct liquefaction of Coal, wherein, as we understand it, the primary Coal oil, Naphthalene, is first hydrogenated to form the solvent, Tetralin, which is then used to hydrogenate and liquefy more raw Coal.. As seen in, and as we emphasize following, excerpts from:. United States Patent 4,476,009 - Improving Hydrogen Donor ...
Coal Mining Machinery Causing Excessive Noise: Worker Deafness Claims UK | Accident Claim Solicitors
There are various different types of machinery used in the coal mining industry which produce excessive noise. The type of machinery used can often depend on the type of mine which is in operation - compare an open cast mine with a deep pit mine and compare working on the surface with working underground.. Some of the typical machinery used underground in coal mining which is known to produce damage to hearing to miners, include:. 1. Face shearers. This machinery is known to produce noise levels sometimes as high as 120 DB and is used to cut along the face of the coal seam - allowing the coal to collapse into a space beneath whilst miners remain at a safe distance in areas supported by beams.. This technique of coal mining is sometimes known as long wall mining as the face shearer runs along the length of the coal face in an underground mine.. 2. Heading cutters. Heading cutters are a type of boring machinery used to bore out tracks in mines for trains to operate along and for other facilities ...
The EPA National Library Catalog | EPA National Library Network | US EPA
Residents of Xuan Wei County in China have unusually high lung cancer mortality that cannot be attributed to tobacco use or occupational exposure. They are exposed to smoke from unvented, open pit coal or wood fires (often used for cooking and heating). The variation in lung cancer rates among communes within the county suggests that indoor combustion of smoky coal may be the prime determinant of lung cancer. To characterize the air in Xuan Wei homes, samples of the air particles and semivolatile organics were collected from homes located in communes with different lung cancer rates. Samples collected in the commune in which the lung cancer rate is high and smoky coal is the predominant fuel contained high concentrations of submicron particles with high organic content; organic extracts of these samples were mutagenic. Samples from homes in a wood-burning commune, which has a low lung cancer rate, consisted mostly of larger particles of lower organic content and mutagenicity. The smoky coal ...

Understanding the salinity issue of coal mine spoils in the context of salt cycle - UQ eSpace
Coal mine spoils (CMSs), the solid wastes originated from the rock formations and soil cover overlying or interbedded with coal seams, are a worldwide environmental management challenge. Previous studies have shown that salinity is of most concern among the CMSs environmental impacts, especially in Australia. With increasing concerns from both the governments and communities, there is a real need for the coal mining industry to understand the source, dynamics and management options of CMS salinity. We reviewed the general properties of CMSs from coal mine sites worldwide and the current understanding of the CMS salinity, which are in a limited number of available published reports. Properties (e.g., pH, electrical conductivity and hydraulic conductivity) of studied CMSs varied largely due to its complex lithological origination. A conceptual model was proposed to illustrate the origin, dispersion paths and transformations dynamics of salts in spoils, taking the scenario of a coal mine in ...

Production of Energy and Chemicals by Thermochemical Conversion from Recycled and Renewable Biomass
Recovery energy from municipal solid waste and biomass are one of the leading methods to achieve maximum energy efficiency and environmental sustainability. My research mainly includes two projects, novel biomass-supported sorbent for coal combustion emission control and fundamental study of biomass fast pyrolysis in the presence of alkaline earth metals. The first research project was collaborated with Accordant Energy LLC. on the development of ReEngineered Feedstock (ReEF), consisting of sorbent containing post-recycled paper and plastics. ReEF was evaluated in a laboratory-scale fluidized bed combustor system. The results indicate that co-firing ReEF with coal provides SO2 reduction in flue gas up to 85% as well as higher carbon conversion than pure coal combustion. Sulfation kinetics of ReEF combustion were evaluated in a drop-tube reactor. Sulfation of calcium hydroxide in ReEF was delayed due to RDF combustion when compared with pure calcium hydroxide sorbent. The second project ...

COAL DESUFURIZATION USING ALKYL ALGINATE (SURFACTANT) - Eprints UPN Veteran Yogyakarta
Sulfur is a component present in coal whose composition is about 1-2% by weight. When coal is used as an energy source it will liberate sulfur oxide or SOx gas. SOx is a highly toxic gas and one of the gases that causes acid rain. Therefore, coal desulfurization is very important to reduce the environmental impact caused by SOx. In this research, coal desulfurization has been conducted using Alkyl-alginate surfactant as surface tension reduction agent in coal washing process. The objective of this study was to determine the concentration of surfactant in washing water and to determine the rate of water flow containing surfactant on the percentage of sulfur reduction. The material used in this research was Indonesian coal from South Sumatera. The selected flow rate variations were 750, 1250, 1500, 2500 and 3750 (ml/min) and surfactant concentrations in range of (0.0625, up to 0.375) grams/liter). The results showed that the largest percentage of coal sulfur reduction obtained at a flow rate of ...
