What is Strip Mining? Methods and Impact

Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the ‘overburden’) are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.
