Techno-Economic Methods to Consider in Designing an Optimal Shaft System in Anglo Platinum

Over the past 75 years, the mining of platinum has predominantly focused on the Merensky Reef horizon in the western Bushveld region of the Bushveld Igneous Complex (BIC) of South Africa (Figure 1). The orebody is relatively flat dipping at 10 to 25, narrow tabular in shape and has been mined to a maximum depth of some 1600 m within Anglo Platinum. This has resulted in the installation of up to four generations of shaft systems as mining progressed into reserves at greater depth._x000D_
In recent years, with the improvement in processing technology and improved economics, in particular with the improved price of palladium, the mining of the UG2 Chromitite Reef is proving economically viable. The UG2 Chromitite Reef occurs below the Merensky Reef in the succession and the normal separation varies from 15 m to 400 m, with the largest separation between the reefs occurring in the eastern region of the BIC._x000D_
The UG2 Chromitite Reef horizon is now being accessed from existing Merensky mining infrastructure by cross-cutting back through the stratigraphy where appropriate, or by establishing new decline cluster systems from surface, along the extensive strike length of the various mining properties. These declines are generally established utilising mechanised mining techniques._x000D_
This paper gives an overview of the techno-economic approaches considered and evaluated for the selection of the optimum mining and shaft systems. More specifically, the paper reviews the design parameters used, techno-economics, conveyor versus haul alternatives, logistics simulations, capital costs, system performance, time to market or ramp-up success, important system differences and lessons learnt.
