Mining coal . Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earths surface, while others are deep mining methods allow coal miners to easily reach most of the nations coal reserves and to produce about three times more coal in one hour than in 1978.
