Coal mining and transportation - U.S. Energy Information

Apr 13, 2022  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.

Coal Processing - CITIZENS COAL COUNCIL

When the coal leaves the mine, it is “dirty”, that is, mined material consists not only of coal, but also of silt, dust, and other non-combustible material. The coal must be processed (or washed) and between 20-50% of the mined material received must be rejected and impounded (National Research Council, 2002; coalimpoundment ).
