Strategic Mine Planning with Surpac & Whittle

This course connects geology to economics. It opens with the theory of strategic planning and pit optimisation: resources and reserves, the Lerchs-Grossmann algorithm, slopes, block value calculation, commodity price, costs, recovery and dilution. You then prepare a Surpac block model for Whittle (rock codes, grades, density, slope regions, costs and adjustment factors) and export the mod and par files. In Whittle you validate the import, reblock, generate pit shells, analyse them with operational scenarios and spider graphs, build schedules with Milawa, and export the results back to Surpac for reporting and pit design.
