Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Coalfired power plants have been identified as one of the major sources of air pollutants in the power sector. Most coalfired power stations have large openair coal stockpiles, which lead to a considerable amount of fugitive dust. The construction of an indoor coal storage is known to control coal dust; however, it requires significant upfront capital. Certain power utilities, including ...

It also has health benefits due mainly to the lower quantity of coal burned per energy generated as well as to small reductions in the sulfur content of coal burned. Cropper's study in fact estimates that washing coal could reduce the number of deaths by 20% per power plant. Currently only 4% of coal in India is washed, and this offers an ...
