About North Antelope Rochelle
The largest coal mine in the United States and among the largest on Earth. Located in the Powder River Basin of Wyoming. Opened in 1983. Produces tens of millions of tonnes of coal per year. The coal seam is thick and lies close to the surface. Powder River coal is low in sulfur, which kept demand high for decades.
