Optimized open pit mine design, pushbacks and the gap
Existing methods of pushback (phase) design are reviewed in the context of "gap" problems, a term used to describe inconsistent sizes between successive pushbacks. Such gap problems lead to suboptimal open pit mining designs in terms of maximizing net present value. Methods such as the Lerchs-Grossman algorithm, network flow …
