Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. This method of coal mining is conducted in the Appalachian Mountains in the eastern United States.
If topsoil substitution were determined to be the best available plant growth material, existing topsoil and subsoil in mined areas would be comingled with overburden during the overburden removal step in the lignite extraction process; it would become fill material for returning the land surface to approximate premining elevations.
