Surface mining Wikipedia

Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad egory 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.
