Abstract
The objective of this research is to estimate the main KPI's of an open pit mining truck and shovel operations, while quantifying uncertainty about the KPI's with high statistical confidence. Short-term production scheduling base their estimations on deterministic approaches, but the nature of mining operation is variable, so when execution of the plan comes, it faces a reality different to what it forecasts. The main contribution of this thesis is to quantify uncertainty in truck and shovel KPI’s due to operational uncertainties, planned and un-planned maintenance, and weather events with a 95% confidence interval. To achieve the research objectives, a discrete event simulation model for truck and shovel operations is built, verified, and validated against historical dispatch data. The following tasks are completed: a) statistical data analysis of historical dispatch data, b) fitting probability density functions on historical operational data, c) building a truck and shovel simulation model in Arena software, d) adding the preventive maintenance, failures, and weather events into the simulation model for trucks and shovels, e) validation of equipment performances against historical data, f) four different major scenarios are assessed with changing the number of ore and waste trucks and the throughput rate of the crusher to find the near optimal size of the fleet, g) the detail short-term expected production of ore and waste under monthly and weekly time frames are reported along with KPI's for tonnage, time charts, availably, and efficiency. The main contribution of this research is a discrete event simulation model for truck and shovel operations that predicts the major KPIs of a mining operation with 95% statistical confidence about the statistics of interest while quantifying the uncertainty around the estimation.
