Coal mining is an industry in transition in the United States. Production in 2019 was down 40% from the peak production of 1,171.8 million short tons (1,063 million metric tons) in 2008. Employment of 43,000 coal miners is down from a peak of 883,000 in 1923. [ 1 ] Generation of electricity is the largest user of coal, being used to produce 50% ...
At the start of the 19th century, coal mining was almost all bituminous coal. In 1810, 176,000 short tons of bituminous coal, and 2,000 tons of anthracite coal, were mined in the United States. American coal mining grew rapidly in the early 1820s, doubling or tripling every decade. Anthracite mining overtook bituminous coal mining in the 1840s ...
The actual average generated power from coal in 2006 was 227.1 GW (1991 TWh per year), [ 14 ] the highest in the world and still slightly ahead of China (1950 TWh per year) at that time. [citation needed] In 2000, the US average production of electricity from coal was 224.3 GW (1966 TWh for the year). [ 14 ]
The following table lists the coal mines in the United States that produced at least 4,000,000 short tons of coal.. According to the U.S. Energy Information Administration (EIA), there were 853 coal mines in the U.S. in 2015, producing a total of 896,941,000 short tons of coal.
Coal mining. Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
The Pittsburgh coal seam is the thickest and most extensive coal bed in the Appalachian Basin; [1] hence, it is the most economically important coal bed in the eastern United States. The Upper Pennsylvanian Pittsburgh coal bed of the Monongahela Group is extensive and continuous, extending over 11,000 mi 2 through 53 counties.
In 1987 Wyoming became the largest coal producing state. It uses strip mining exclusively. Wyoming's coal reserves total about 69.3 billion short tons (62.9 Pg), or 14.2% of the U.S. coal reserve. [69] In 2008, competition was intense in the US coal mining industry with some U.S. mines approaching the end of their useful life (mine closure).
As of 2019 G20 countries provide at least US$63.9 billion [175] of government support per year for the production of coal, including coal-fired power: many subsidies are impossible to quantify [195] but they include US$27.6 billion in domestic and international public finance, US$15.4 billion in fiscal support, and US$20.9 billion in state ...
