Long-term open pit mine production planning: a review of models and algorithms

摘要: Long-term production planning (LTPP) is a large-scale optimization problem that aims to find the block extraction sequence produces maximum possible net present value (NPV) whilst satisfying variety of physical and economical constraints. The economic feasibility mine highly dependent upon careful LTPP. As mining industries extract deeper lower grade ores, LTPP becoming key item can result in ceasing operations or continuing project. Mathematical programming models are well suited optimizing open pit mines. These mathematical have been studied extensively literature since 1960s. this study shows there two approaches for dealing with problems: (1) deterministic (2) uncertainty-based approaches. This paper first discusses algorithms then, after an introduction uncertainty associated projects, reviews algorithms. advantages disadvantages these...
