Resumen

ESTERHUIZEN, A.. Unique fall-of-ground prevention strategy implemented at Two Rivers Platinum Mine. J. S. Afr. Inst. Min. Metall. [online]. 2014, vol.114, n.10, pp.785-790. ISSN 2411-9717.

Since 2005 Two Rivers Platinum Mine has set out on an initiative to actively monitor and control ground conditions on a daily basis, by making use of borehole cameras and pro-actively amending the support and mining strategies based on day-to-day observations of the hangingwall conditions. Today the borehole camera observations form part of the Rock Engineering Department's daily function, and the size and frequency of falls of ground and ensuing accident rates have been drastically reduced since implementation of the system. The Two Rivers Platinum fall-of-ground management system aims to support 100% of the possible fallout thickness, based on ongoing data gathering and interpretation, thereby ensuring safety and limiting support cost.
