Mine-to-mill (M2M) optimisation is a mature methodology that has demonstrated significant benefits to operations globally. One drawback to the approach is that the audits conducted to calibrate the blasting and comminution models only capture an instant in the operation’s life. This can limit scenarios where there are complex ore paths or long-term schedules to be considered.
The authors have developed a methodology to simulate concentrator performance for each block in the life-of-asset model using different blast designs. This enables a site to understand where and when the potential for throughput increases can occur, as well as making M2M sustainable in the long term. In this paper, the authors describe the approach and tools used in this project.
