Hierarchical mine production scheduling using discrete-event simulation

0
Mine planning involves different levels of decision-making depending on the time horizon under consideration. The main goal of this study is to develop a discrete-event simulation model to link long-term predictive mine plans with short-term production schedules in the presence of uncertainty. We have developed, verified and validated a discrete-event simulation model for open pit production scheduling using the SLAM simulation language. The simulation model takes into consideration constraints and uncertainties associated with mining and processing capacities, crusher availability, stockpiling strategy and blending requirements. Application of the simulation model is presented by an iron ore open pit mine case study.
