OpenPit Mining. Open pit mining is the process of mining any nearsurface deposits by means of a surface pit excavated using one or more horizontal benches. Open pit mines are often used in mining metallic or nonmetallic deposits and more sparingly in coal and other bedded deposits.
Openpit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, openpit mining consists of a system to exploit open pits with multiple benches.
