Integrated open pit pushback selection and production capacity optimization

Strategic mine planning for open pits has now evolved to the simultaneous optimization of a number of decisions and this leads to the consideration of additional solutions, with the potential to add value to planning and reduce manual data transfer time. Unlike previous efforts, this paper outlines a method for simultaneously optimizing mining and processing capacities, including intermediate and ultimate pushback selection, with the determination of scheduling, cut-off grade, and stockpiling to maximize net present value.
