Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, while others are deep 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.

The steam then turns a turbine attached to a generator and electricity is produced. Coal is also used in industry for other uses. For making steel, coal is used in blast furnaces to make heat to melt steel. Coal is heated with steam and the gas that is produced is distributed as demotic/industrial gas in some old cities.
