Coal mining, extraction of coal deposits from the surface of Earth and from underground.. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal ...
The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained …
India has the fifth largest coal reserves in the world. As on 31 March 2017, India had 315.14 billion metric tons (347.38 billion short tons) of the resource. The known reserves of coal rose 2.05% over the previous year, with the discovery of an estimated 6.34 billion metric tons (6.99 billion short tons).
Pollution from coal mining may have a negative impact on public health in mining communities, according to data analyzed in a West Virginia University research study.
International Journal of Mining Science and Technology is an English-language journal.

EPA promulgated the Coal Mining Effluent Guidelines and Standards (40 CFR Part 434) in 1975, and amended the regulation in 1976, 1977, 1979, 1982, 1985 and 2002.The regulation covers wastewater discharges from mine drainage, coal storage facilities, and coal preparation plants.
A key National Academies of Sciences, Engineering and Medicine study on coal mining in the Appalachian Mountains is under review over whether it's worth the money.
Coal: Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in …

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Hurriers were as vital to the operation of a colliery as were the colliers. They were invariably children or women and as in textiles and many other trades in the industrial revolution, coal mining could not have developed without the exploitation of this source of labour power.
