Coal Mining and Production Industry Description and Practices Coal is one of the world's most plentiful energy resources, and its use is likely to quadruple by the year 2020. Coal occurs in a wide range of forms and qualities. There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other
At each stage of the coal production and use cycle, water is polluted at levels that significantly harm water quality, ecosystems and human health. Heavy metals and toxins such as mercury, lead and arsenic are found in coal ash, coal slurry and coal waste, which when improperly managed can contaminate groundwater, rivers and seas.
Ideally, coal slurry consists only of crushed coal and water, which can be efficiently separated. In practice, the separation is significantly costly due to the large amounts of water needed and wastewater generated by the process. Furthermore, the slurry consists also of very fine coal dust that results in a waste called blackwater.As blackwater cannot be purified by a water treatment plant ...

Coal burning generates coal ash that is stored in landfills and slurry ponds that are often located near residential communities, signifying high potential for environmental contamination and increasing health risks. We reviewed the literature on potential health effects of coal-burning plants to summarize current knowledge on health risks.
In the early morning hours of December 22, 2008, the earthen wall of a containment pond at Tennessee's Kingston Fossil Plant gave way. The breach released 1.3 million cubic meters (1.7 million cubic yards) of fly ash —a coal-combustion waste product captured and stored in wet form. As fly ash dries, it is typically moved to new containment areas to continue drying, and it was one of these ...
