Potvin %C Perth %8 7-9 November %B Deep Mining 2007: Proceedings of the Fourth International Seminar on Deep and High Stress Mining %X The extension of the life of some shafts by mining extractable, accessible and economically viable remnant pillars, has become much of a necessity. The geotechnical investigation into the potential for successful extraction of these pillars is crucial, and is approached in a multi-disciplinary manner. This case study outlines the mining methodology, and relates the initial investigation to the practical experience of extracting a 8000 m2 remnant pillar in a tabular reef at 1600 m depth, at the Thabelang “Let’s be happy” Shaft of Gold Fields’ Driefontein mine. %1 Perth %I Australian Centre for Geomechanics %U https://papers.acg.uwa.edu.au/p/711_11_Wienand/ %R 10.36487/ACG_repo/711_11
