The North Antelope Rochelle Mine is the second largest coal mine in the U.S. Located in Campbell County, Wyoming, about 65 miles south of Gillette, it produces 107,700,000 tons annually. The company started work on the site in 1983 and the mine was opened in 1984. We used draglines and trucks and shovels to remove the overburden. Trucks then haul the coal from the three pits to trains for shipment to customers. In 2012 the Morrison Knudsen won an award from the Department of the Interior for its reclamation efforts over the life of the mine.
