Optimized open pit mine design, pushbacks and the gap

Dec 04, 201410%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 techniques, the fundamental

Types of Mining Methods

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.
