(University of Pretoria, 2015)Crush pillars are used as part of the stope support in intermediate depth tabular mining stopes. Crush pillar design should ensure that the pillars crush when formed at the mining face. This behaviour of the pillars is ...
-
(University of Pretoria, 2015)In mining, the loading environment on pillars is highly complex with combinations of normal and shear stresses. It is also understood that with an active and working face, constant redistribution of stresses will occur to ...
-
(University of Pretoria, 2013)Scattered mining was practised on Kusasalethu Mine (previously Elandsrand Gold Mine) prior to 1998, but as mining proceeded deeper, it was no longer a feasible option. The scattered mining method would have resulted in ...

Structural mechanisms contributing to large-scale hangingwall instabilities on the UG2 reef horizon (University of Pretoria, 2019)Structural complexities, including regional geologic structures, low-angle structures, ramp structures and alteration zones contribute towards large-scale hangingwall or structural (pillar) instabilities experienced in ...
