Mined coal.

What is coal used for? Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. The term, surface mining, describes all procedures that remove the surface to reach mineral deposits. This method includes open-pit and strip mining, and is used to reach cinder, gravel, and sand.
