Application to compare of open pit grade control systems
In open pit mining, grade control and ore grade reconciliation relate to practices of comparing the values of grade estimation in exploration stage with actual grade obtained from production data. These activities are aimed at identifying, analysing and managing variance between planned and actual results to ultimately highlight opportunities for improvement. The opportunities commonly include: methods to create better estimates, improved designs, tighter and more accurate plans and schedules, improved mining techniques to minimise ore loss and dilution and identifying ways to increase metal recoveries during the extraction processes.
Years of practice and research have yielded various systems that claim to produce optimal ore/waste block boundaries by analysing uncertainty using multiple grade realisations from geostatistical or stochastic simulations. However there has been no comparative analysis of these methods to determine whether one is better than the other. As such the objective of this project is to produce an application that can compare the outputs of by these systems and ultimately identify the system that provides the most desirable solution under certain open pit conditions.
