Millsell Mine has one of the most structurally disturbed geological areas in the western limb of the Bushveld Complex. The occurrence and high frequency of geological structural elements within the mining area requires careful design considerations and proactive strategies to maintain a stable production system. The mine invested in Ground Penetrating Radar (GPR) technology to detect the presence of structural elements within the hanging wall strata. This technology is supported by design considerations that seek to protect the integrity of the excavations thereby reducing the number of uncontrolled Falls of Ground (FOG). To this end, the mine has been able to reduce the number and size of FOGs through the application of new mining strategies to negotiate geological structures in a safe and acceptable manner.
