613· Strip mining involves the removal of strips of soil and rock to expose the mineral deposits. While open-pit is similar, the excavation is much deeper, and the mining is done on a larger scale. Mountaintop mining, however, involves the use of explosives to remove the top of a mountain and enable access to the minerals underneath.

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.

Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, [1] is a surface mining technique that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin.
