Where the United States gets its coal
In 2021, about 577 million short tons of coal were produced in 21 U.S. states. Surface mines were the source of 62% of total U.S. coal production and accounted for 65% of the total number of producing mines. About 0.6 million short tons, or less than 0.1% of total coal production, was refuse recovery coal. Five states accounted for 74% of total U.S. coal production in 2021.
- The top five coal producing states and their percentage shares of total U.S. coal production in 2021 were:
- West Virginia14%
Coal is mainly found in three regions: the Appalachian coal region, the Interior coal region, and the Western coal region (includes the Powder River Basin).
The two largest coal mines in the United States are the North Antelope Rochelle and Black Thunder mines in Wyoming. Together, the two mines produced 21% of total U.S. coal production in 2021. The North Antelope Rochelle mine alone produced nearly the same amount of coal in 2021 as the states of Illinois and Montana combined, the fourth and fifth largest coal-producing states.
