Many references to coal mining in England and Scotland and on the European continent began to appear in the writings of the 13th century.

Coking coal, also known as metallurgical coal, is used exclusively as an essential ingredient for steel production. The coal is 'baked' in a coke oven which forces out impurities to produce coke, which is a form of almost pure carbon.

Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines.
