Coal mining and transportation U.S. Energy Information

2020-12-10  Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern 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.

12 Environmental Effects of Coal Mining Environment 911

There is much debate whether the environmental effects of coal mining justify its continued use. Coal is either extracted from deep inside the earth or removed from its surface. The former is known as underground mining, the latter as strip mining or mountaintop removal. Either process contributes a high level of damage to the environment:
