Particularly at the earlier stages of a rock engineering project, the lack of appropriate data manifests itself in the form of increased uncertainty and difficulties in characterizing rock mass variability in an objective manner. When mine-scale problems are considered, it is not possible to sample all of the rock mass, therefore a relative large number... Continue reading.
This presentation will cover the evolution of block size distribution (BSD) within a draw column during block cave mining. BSD plays an important role in controlling gravitational flow, secondary fragmentation, and fines migration in broken ore—all of which are fundamental in preparing a reliable feasibility assessment for a potential caving operation. However, there is a... Continue reading.
The industry perception is that sublevel caving is a “dirty mining method” (i.e. high dilution and low recovery). However, there were several successful sublevel cave mines executed in the past. The success of a sublevel cave mine is not by chance – they are engineered to perform. This talk will review some of the recent... Continue reading.
