Investigations into the residual strength of a 2.5 m wide Bushveld Merensky Reef crush pillar

Author: Watson, BP ; Mosomane, SM ; Kuijpers, JS ; Roberts, David P Date: Aug 2008 The first crush pillars on the Bushveld platinum mines were introduced at Union Section in 1978. Before the introduction of crush pillars, serious problems were experienced when stoping advanced to a point 30 m to 40 m on both sides of the ... Read more
Merensky pillar strength formulae based on back-analysis of pillar failures at Impala Platinum

Author: Watson, BP ; Ryder, JA ; Kataka, MO ; Kuijpers, JS ; Leteane, FP Date: Aug 2008 The Bushveld platinum group metal deposits are two distinct, shallow-dipping stratiform tabular orebodies and strike for many hundreds of kilometres. Mining is extensive, with depths ranging from close-to-surface to 2 000 m. The mining method ... Read more
Nonlinear rock behavior and its implications on deeper-level platinum mining

Author: Watson, BP ; Kuijpers, JS ; Henry, G ; Palmer, CE ; Ryder, JA Date: Oct 2008 Uniaxial tests performed on core from instrumented sites at Amandelbult 1 shaft, Impala 10 shaft and Union Section Spud-shaft showed a nonlinear elastic relationship between applied load and induced deformation. This nonlinear behaviour does ... Read more
Performance of various types of containment support under quasi-static and dynamic loading conditions, Part I.

Author: Kuijpers, JS ; Milev, AM ; Jager, AJ ; Acheampong, E Date: May 2002 Seismicity causes the most severe loading conditions for tunnel support systems in deep-level South African gold mines. The design of such support systems should therefore incorporate the potential effect of seismicity on support requirements. ... Read more
Stope face support systems

Author: Daehnke, A ; Andersen, LM ; De Beer, D ; Esterhuizen, GS ; Glisson, FJ ; Grodner, MW ; Hagan, TO ; Jaku, EP ; Kuijpers, JS ; Kullmann, AV ; Peake, PS ; Piper, PS ; Quaye, GB ; Reddy, N ; Roberts, MKC ; Schweitzer, JK ; Stewart, RD ; Wallmach, T Date: Dec 1998 The primary output of this report was the determination of geotechnical areas across the gold and platinum mines to form the basis for future understanding of the rock mass behaviour around reefs where the hanging wall and footwall rock types ...
