Strip mining. is for minerals that are just below the surface. Soil and rocks are removed, and the resource is extracted. ... Open-pit mining. is used for deep underground minerals that are found in a large area but are unsuitable for subsurface mining. Open-pit mining digs a hole in the earth, extracting the mineral. Mountaintop removal.
What is Strip Mining? 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.
