Improved understanding of the use of short tendons for stope support under rockfall and rockburst conditions, (Phase I).

Author: Roberts, David P ; Roberts, MKC ; Acheampong, E Date: Mar 2002 The aim of this project was to determine whether the introduction of short bolts into a stope hangingwall would increase the stability of the hangingwall beam. A simple physical 1/10th hangingwall model was constructed out of concrete, with ... Read more
Investigate the rock mechanics aspects of potholes in the platinum mines, their contribution to poor ground conditions, and if proactive identification is possible

Author: Urcan, H ; Grodner, M ; Watson, B ; Lamos, RA ; Roberts, MKC ; Stewart, R ; Squelch, AP ; Le Grange, R ; Xaba, D Date: Jul 2003 The main aim of this project was to define and quantify the effect of potholes on ground conditions in platinum stopes, and assess whether these changes could be used to predict the occurrence of potholes ahead of stope faces. In order to ... Read more
Rock Mechanics Aspects of Stoping Without Back-area Support

Author: King, RG ; Jager, AJ ; Roberts, MKC ; Turner, PA Date: Jun 1989 The report describes an experiment carried out at Hartebeesfontein Gold Mine, No. 6 Shaft, 77 N 25 Stope between October 1985 and November 1986, which involved mining two panels without back-area support and with different support resistances ...

Stope and Gully Support: Final report

Author: Roberts, MKC Date: Dec 1995 This project had two objectives namely: Develop a rationale for the design of stope support systems. Determine support resistance criteria for the support of stope gullies for both static and dynamic loading and develop improved support systems ... 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 ...

Violent failure of a remnant in a deep South African gold mine

Author: Durrheim, RJ ; Haile, A ; Roberts, MKC ; Schweitzer, JK ; Spottiswoode, SM ; Klokow, JW Date: 15 Apr 1998 The violent failure of a peninsular remnant at a depth of 2300 m below surface occurred in a mine in the Carletonville Goldfield of South Africa, severely damaging a stope mining the Ventersdorp Contact Reef (VCR). At the rockburst site the ... Read more
