What are the types of coal? - USGS

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. In 2019, about 23 percent of...

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Coal in the U.S. and Indiana | Indiana Geological & Water Survey

Production of sub-bituminous coal began to slowly rise; as of 2010 it was higher than bituminous coal production. Until the 1950s coal was primary mined underground east of the Mississippi River. By the 1970s, the development of cheaper surface mining proved a viable alternative for the coal industry.

Subbituminous and bituminous coal dominate U.S. coal

While almost all coal consumed in the United States is used to generate electricity (90% in 2010), coal is not entirely homogeneous. Coal is classified into four types, distinguished by the amount of heat it produces and, for coking coal, its ability to agglomerate. While coal with higher levels of heat content, coking characteristics, and lower sulfur levels is typically more valuable, other factors such as location and supply and demand play a significant role.

Coal Production - an overview | ScienceDirect Topics

Coal was exported to other European countries by 1325 as a result of widespread mining with increased coal production from 2.27 to 9.07 million mt during 1700–1800 (Eavenson, 1939). The Industrial Revolution, confined in Great Britain from 1760 to 1830, increasingly utilized coal to make coke for smelting iron and other metals and to fuel ...
