A Mine Planning Tool to Facilitate Planning Under Uncertainty.

Traditional mine planning is based upon maximizing the Net Present Value (NPV) of the forecast production outcomes from the mine. This methodology does not consider intrinsic uncertainty/variability of the mining system. Thus, when NPV oriented plans become operational there are large deviations with respect to the production rates, sequences and cut off grades, which derives in causing inefficiencies that lead to a lack of productivity and an increased operating cost
