A stochastic mine planning approach to determine the …
the open pit operation is massively aggregated into bench-wise panels within predesigned pushbacks. The underlying assumption of the homogeneous mining of panels misrepresents the selectivity of open-pit mining. Whittle et al. (2018) extend the so-called opportunity cost approach for determining the open pit to underground mining transition. In ...
