The state that is the largest producer of coal from mountaintop removal mining is West Virginia.

Mountaintop removal mining (MTR) is a form of surface mining predominantly used in the Appalachian region, where coal seams are located close to the surface. West Virginia is the leading state in MTR coal production, due to its abundant coal reserves and long history of mining. This controversial method involves removing the summit of a mountain to access coal seams, which can have significant environmental and ecological impacts, including habitat destruction and water pollution.
