Optimal production scale of open pit mining operations with uncertain metal supply and long-term stockpiles
Published 2012“…This work proposes an extension to an established theory of cutoff grade to determine the optimal production capacities using a stochastic framework relying on multiple realizations of the grade-tonnage curves. The proposed model (i) maximizes the net present value of cash flows over the life of an operation; (ii) offsets the initial investment in developing the constituent stages of an operation; and (iii) explores the impact of creating a long-term stockpile on the designed operational capacities. …”

An Investigation to Integrate Optimum Long-Term Planning with Short Planning in Underground Mine Production Scheduling
Published 2010“…A case study is presented which compares the present values of the same stope data set scheduled via separate long and short-term models and than by the proposed integrated model which applies a predetermined penalty for each tonne of metal deviation to target for the respective ore tonnage being processed. This allows an operation to obtain a globally optimal scheduling regime when taking into consideration the cost and loss of value resulting from fluctuations in grade to the mill over the short-term.…”
