There are 5 main types of surface mining, which are used in various degrees and for different resources. These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is when soil and rock overlying the mineral deposit (the overburden) are removed. The surface miner is a mobile milling machine with a mechanically driven cutting drum used to remove the overburden.
