Coal, Mining, Reclamation
Coal production is the amount of coal that is mined and sent to market. In 2008, the amount of coal produced at U.S. coal mines was 1,171.8 million short tons. Coal is mined in 26 States. Wyoming mines the most coal, followed by West Virginia, Kentucky, Pennsylvania, and Texas.
Coal is mainly found in three large regions, the Appalachian Coal Region, the Interior Coal Region, and Western Coal Region (includes the Powder River Basin).
More than one-third of the coal produced in the United States comes from the Appalachian Coal Region. West Virginia is the largest coal-producing State in the region, and the second largest coal-producing State in the United States. This region has large underground mines and small surface mines. Coal mined in the Appalachian coal region is primarily used for steam generation for electricity, metal production, and for export.
Coal is used to create almost half of all electricity generated in the United States. Power plants burn coal to make steam. The steam turns turbines (machines for generating rotary mechanical power) that generate electricity.

Types of Coal
Lignite is the lowest rank of coal with the lowest energy content. Lignite is crumbly and has high moisture content. Lignite accounts for about 7% of U.S. coal production.
Subbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35-45% carbon, compared to 25-35% for lignite. About 44% of the coal produced in the United States is subbituminous.
Bituminous coal contains 45-86% carbon and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure It is the most abundant rank of coal found in the United States, accounting for about half of U.S. coal production.
Anthracite contains 86-97% carbon and has a heating value that is, on average, slightly higher than bituminous coal. It is very rare in the United States, accounting for less than 0.5% of the coal mined in the United States.
