Open Pit Mining - an overview | ScienceDirect Topics

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
