Wyoming’s Coal Resources

Wyoming is the largest producer of coal in the United States. Coal resources are abundant in many of Wyoming’s geologic basins, particularly in the Powder River Basin (PRB) with its 13 surface mines and up to 100 feet thick coal seams.

Between 50 and 70 coal trains per day leave the PRB loaded with coal to destinations mostly south and east of Wyoming. Coal is mined in the PRB at a rate of 12 tons per second, supplying the nation with 400 million tons of coal annually. Nine of the nation’s 10 largest coal mines operate in the PRB. With the state’s mines combined, Wyoming produces as much coal as the next top six coal-mining states combined (West Virginia, Kentucky, Pennsylvania, Illinois, Texas, and Montana).
