The North Antelope Rochelle Mine is the largest coal mine in the world.[1][2] Located in Campbell County, Wyoming, about 65 miles south of Gillette, it produced 85.3 million tons of coal in 2019.[3][4]
Peabody Energy opened the North Antelope Mine in the heart of Wyoming's Powder River Basin in 1983.[5] The Rochelle mine was opened in 1984. They were combined in 1999, making the largest coal mine in the United States. A contender for the title of largest mine emerged in 2009 when Arch Coal, the owner of the Black Thunder Coal Mine bought the Jacobs Ranch Mine. These two operations merged and North Antelope Rochelle ceded the title of largest mine to Black Thunder in 2012.[6]
