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.

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.
Open pit mining is a technique used to extract copper ore near the earth''s surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth''s surface. Underground mining is used when the copper ore is not near the earth''s ...
Expanding the open pit and operation of mining machinery create dust, which, due to the terrain configuration around the open pit, is dispersed by wind currents in the urban area. Dust and gases are emitted by the mining equipment operation at the open pit dust and atmosphere of the open pit .
