Efficient OperationsOne of the major benefits to open pit mining is the increase in efficiency over deepshaft mining techniques. Because mining occurs at the surface, no space restrictions from narrow tunnels and shafts affect the rate at which ore can be extracted. Sampling each "bench" or level in an open pit before mining deeper makes it easy for surveyors to analyze the potential ...
Openpit, opencast 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 mines are used when deposits of commercially useful ore or rocks are found near the surface.
