Guidelines for Open Pit Slope Design 3 Design Edumine
The design of the slopes is one of the major challenges at every stage of planning and operation of an open pit mine. It requires specialised knowledge of the geology, which is often complex in the vicinity of orebodies where structure and/or alteration may be key factors, and of the material properties, which are frequently highly variable.
Information evaluationOpenpit mining Wikipedia
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 mining.Openpit mines are used when deposits of commercially useful ore or rocks are found near the surface.
