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 …
Pit optimisation
Did you know?
WebABSTRACT: The open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 40 years The development of the "know-how" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 1960's. Webimported into Whittle for the open pit optimisation, based on geotechnical and economic parameters derived from calculations or assembled from mines operating in Ghana. The optimal pit is then imported back to Surpac for detailed pit design incorporating a ramp and berms. The designed pit contains 5.03 Mt of ore at an average grade of 1.7063 g/t.
