The surface mining can be classified depending on the location of the deposit or the type of mining method. Generally speaking, we can classify surface mining in three main typologies that are open pit, open cast, and quarry. Open pit refers to the exploitation of a deposit outcropping to the surface .

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which ...
