Coal explained Mining and transportation of coal
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, but others are deep underground.Modern mining methods allow U.S. 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 …
