1. Introduction. Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al., 1997).In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of ...

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.
