Surface mining Wikipedia

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.

Strip Mining an overview ScienceDirect Topics. When associated with canyon fill, steep slopes that can be very erosive are formed. Surface mining produces more solid waste than underground mining techniques, with 10 tons of solid waste produced per 1000 tons of coal removed for both contour and area mining (World Bank Group, 1998).
