MSAHP: An approach to mining method selection
The mining factors -extraction, mining height, overbreak dilution, and mining losses - are under the control of the mining engineer, subject to constraints imposed by the mining method. As such, these factors are not selection criteria per se and are used in MSAHP mainly to test the robustness of the mining method ranking order in the face of ...
