Surface mining, or open pit mining, is another way to extract coal. This method is conducted on hillsides and is visible from the exterior. In open pit mining, exposed coal is blasted and then removed by giant shovels (Edmunds, 2002). Surface mining exposes the coal by a means of striping away the ground concealing it (Clark, 2011).

The mining of coal is by the "pillar and breast" system. When the gangway and airway have been driven two or three hundred feet chambers are opened at right angles to the airway,—these are called "breasts." A narrow tunnel, just wide enough to admit a mine-car track, is driven about fifteen feet, beyond which the breast is opened to its full ...

Underground mining. In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. …

Specimens of frugivorous bat species Artibeus lituratus and Sturnira lilium were collected from an area free of coal dust contamination and from coal mining areas. Chemical composition, histological parameters, synthesis of oxidants and antioxidant enzymes, and oxidative damage in the lungs of bats were analyzed.

In the United States, coal accounts for roughly one-quarter of all energy-related carbon emissions. 2. Air Pollution. Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, and other severe environmental and public health impacts.

View PDF. Coal mining Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
