A complete strategic open pit mine planning system – NPV Scheduler has functionalities spanning everything from pit optimisation, pushback generation, cut-off grade optimisation, scheduling, haulage optimisation and stockpile management. The advanced system caters for alternative techniques beyond NPV for pit optimisation to take account of material blending requirements or to maximise mine life. The innovative pushback generator delivers the most practical pushbacks of any competing product and the scheduling capability includes optimisation techniques that look ahead to the entire life of the mine as opposed to considering just one period at a time.
