Parametric maximum flows and the calculation of optimal intermediate contours in open pit mine design
The open pit mine design problem is that of deciding which blocks of an ore deposit should be mined so as to maximize total profit while respecting certain digging constraints. In this article we show, through a parametric maximum flow analysis, how intermediate contours should be mined so as to maximize the benefit-cost ratio while proceeding toward the ultimate mine contour.
