INTRODUCTION The selection of mass mining methods is the situation facing not only planners of new operations, but also those involved with cur- rent operations, including the eventual change from open-pit to underground. Increasing ground control problems on many mines, plus a better understanding of dilution and ore loss problems have meant a review of …

The optimal mining method has the highest priority percentage. The results of these adjustments for the cost criteria can be seen in Table 8. Results show that the optimal mining method selection continues to be the SM mining method until the of cost priority percentage is increased by approximately 20 %.
Mining method selection is the most fundamental activity of a mining study, because everything else depends on it. It is a process whereby the mining method attributes are matched to the orebody characteristics. ...
