Basics of an open pit mine - Mine Engineer.Com

The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.


There are two main methods used in coal extraction: surface mining (above the ground) and subsurface mining (below the ground). Location is the biggest factor in determining what method will be used. Normally surface mining occurs west of the Mississippi river and subsurface occurs to the east.
