Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
Quarry. A quarry is a kind of open-pit mine from which rock or minerals are extracted. Quarries are normally utilized for extracting building materials, like dimension stone. Quarries are normally shallower than other kinds of open-pit mines. Quarries are also at times used as filming locations.

Planning of open-pit mines on a business-risk basis (2) emphasizes that confidence for slope design should be categorized using the same fundamental approach as that adopted for resource definitions–such as proven and possible reserves. For example, a proven slope angle requires that the continuity of the stratigraphic
