Abstract :Mathematical modelling, and optimization are efficiently used in open pit mining problems, as it is the case of other engineering areas, business, and economic disciplines. One of the problems in this context is related to the role of stockpiles to serve maximization of the profit and minimization of the costs. In this paper, a short-term production plan for a mine-mill operation having a stockpile area is developed. The approach is based on network diagrams and linear programming method. Data set used in the application is hypothetical considering two months of duration. In the scenario, the milling facility nearby the mine is subjected to two stages material feeding located in the mining and milling areas. The objective is to minimize the costs while fulfilling the demands of the milling unit. LINGO software is used to evaluate the mathematical model. From the results of this study, it is concluded that there is no need for stockpiling operation at mill area for the stage 2 production process and the stockpile at mine area is required to satisfy the stage 1 production demand of 6,000 tons in month 2.
