Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks ...
the full width and height of the ore but leaving pillars for support of the back. The level plan thus becomes the ore outline. If the shaft is sunk outside the ore body, a short connecting crosscut from the shaft, and perhaps others to separate ore bodies, constitute all the development work required, the ore being mined as the workings advance.
