Abstract:
This paper discusses a new software tool developed specifically for use in a sublevel caving project/mine. The tool includes a number of new algorithms or technologies which when combined provide a very efficient way to evaluate a complete sublevel layout in a matter of seconds. The core technologies imbedded in the tool are simulation of material mixing for dilution forecasting using Template Mixing algorithm, optimisation of the draw factors or extraction percentages per ring, and rapid sequencing/scheduling of the resulting ore tonnages. Examples are presented showing how the rapid analysis can allow sensitivity studies on tunnel spacing, mining rate and economics, face shapes and draw or extraction strategies. A real-world example from the DeĀ Beers Venetia Underground project is presented. Concluding remarks will discuss how this new tool fits in with the existing industry tools for open pit, open stope, block cave and sublevel cave operations optimisation. Keywords: orebody evaluation, SLC mining method evaluation, SLC footprint assessment
