Author:Linzer, LM; Watson, BP; Kuijpers, JS; Acheampong, EDate:Mar 2002Results of SIMRAC project GAP 223 showed that stabilizing pillar-related back area seismicity was not related to the width of the pillar, nor to the dip spans of the stopes supported by the pillar. Pillar associated seismicity initiated in ...Read more

Author:Schutte, PC; James, JPDate:2007Ergonomic surveys are conducted to identify ergonomics-related risk factors in a workplace. The surveys include elementary hazard identification, risk assessment and identification of areas where specialist ergonomics advice is required. This ...Read more
Author:Smith, JR; Shaba, MN; Marais, P; Schutte, PC; Mac Duff, L; Malapane, MC; Harper, GS; Romoshebi, JDate:Mar 2002This research report discusses the ergonomics of locomotive designs in South African gold and platinum mines. The purpose of the study was to identify safety aspects of the existing fleet of mine locomotives and rolling stock that could be ...Read more
Author:Peake, AV; Ashworth, SGEDate:Oct 1996This project reports on the findings of an investigation into reasons why hanging wall examination procedures fail to prevent fall of ground accidents on gold and platinum mines. Ideally, these procedures should identify every unsafe hanging ...Read more
Author:Hlophe, KDate:31 Aug 2010South Africa plays a major role in the international mining fraternity. Location information will enhance the safety in mines by permitting the realisation of wireless sensor networks (WSN), which are persistent and ubiquitous environmental ...Read more
Author:Watson, BP; Ryder, JA; Kataka, MO; Kuijpers, JS; Leteane, FPDate:Aug 2008The 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
Author:Vogt, D; Brink, VZ; Schutte, SDate:Sep 2009South African underground hard rock mines are typically managed using measurements made daily, weekly or even monthly of key parameters like face advance, readiness to blast, blast success, temperature or dust levels. Safety and health can ...Read more
Author:Edwards, ALDate:31 Aug 2010Noise-induced hearing loss (NIHL) negatively affects the quality of life of mine employees and costs mining companies large amounts in compensation claims. The prevention of NIHL requires early identification and recent evidence about the ...Read more
Author:Lightfoot, N; Maccelari, MDate:Mar 1999This report covers the production of a general reference handbook of numerical
modelling for the South African mining industry, with particular reference to the gold and platinum industries. It also covers a research sub-project investigating ...Read more
Author:Durrheim, RJ; Ogasawara, H; Nakatani, M; Yabe, Y; Milev, AM; Cichowicz, A; Kawakata, H; Moriya, HDate:Oct 2010Mining-induced earthquakes pose a risk to workers in deep South African mines, while natural earthquakes pose a risk to people living close to plate boundaries. The authors introduce a 5-year Japanese - South African collaborative project ...Read more
Author:Pretorius, CDate:May 2010In view of the international drive to eliminate silicosis, it is critical that reliable and consistent results are obtained from respirable dust sampling and analysis so that effective control measures can be implemented on mines. Two locally ...Read more
