20191030&ensp·&enspOpenpit, 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.

Longterm production scheduling modeling for the open pit
Abstract. The economic consequence of the modern day mine is highly dependent on careful management of cash flows and risk during production. Mine planning is a critical mechanism at all stages in the life of an open pit mines that major element of mine planning is the optimization of longterm production scheduling problem (LTPSP) within operational constraints such as mining slope, grade
