Maptek™ Vulcan™ Pit Optimiser has provided a solution for MEC Mining in the completion of a feasibility study for a steeply dipping resource in a complex metallurgical coal project. The Pit Optimiser was the ideal solution for assessing the economic value for a coal project and providing the basis for detailed design and scheduling work.
The coal deposit contained 5 seam groups, 3 major overthrust faults and shears, and normal faults in a single pit. Information supplied included a block model, economic assumptions and a geotechnical assessment. Margin rankings provided some clarity on basal seam and economics.
The aims of the feasibility study were to define the location of the final highwall, low wall and basal seam. In this instance of multiple occurrences of single overlapping seams, Maptek’s Pit Optimiser provided a ‘shortcut’ to the basal seam. Running advanced reserves in Vulcan validated the volumes and the final block model.
