Author:Napier, JAL; Malan, DF; Sellers, E; Daehnke, A; Hildyard, MW; Dede, T; Shou, K-JDate:Dec 1998The investigation of the behaviour of the fracture zone surrounding deep level gold mine stopes is detailed in three main sections of this report. Section 2 outlines the ongoing study of fundamental fracture process and their numerical ...Read more
Author:Spottiswoode, SM; Linzer, LM; Majiet, SDate:Sep 2008The researchers analysed seismicity in two deep gold mines in terms of strain energy release during mining. Mining took place with regularly-spaced dip pillars and backfill for regional support. The mines were chosen to represent mining of ...Read more
Author:Malan, DF; Grave, M; Napier, JAL; Piper, PS; Lawrence, LEDate:Mar 2003Previous fundamental research projects have indicated the value of continuous closure measurements for improved support design and hazard assessment and for quantifying the effect of seismicity on stope closure. This project examined the ...Read more

Author:Durrheim, RJDate:Sep 2014The remarkably rich and persistent gold and platinum deposits in South Africa stimulated the development of a deep mining industry. The challenges of mining laterally-extensive orebodies at depths as great as 4 km include high rock stress and ...Read more
Author:Hobbs, PJ; Cobbing, JEDate:Aug 2007The comparatively short history of acid mine drainage (AMD) in the West Rand Basin (WRB) via mine water decant on the Randfontein Operations property (formerly Randfontein Estates Ltd) of Harmony Gold Mining Company west of Krugersdorp (Figure ...Read more
Author:Oosthuizen, MA; John, J; Somerset, VDate:2010The objective of this study is to establish whether a specific community in a gold mining area, with potentially associated small-scale gold mining activities, was exposed to mercury. The community was situated in Mpumalanga, where some ...Read more
Author:Vogt, D; Brink, VZ; Brink, S; Price, M; Kagezi, BDate:01 Sep 2010Rockfalls are responsible for more than 30 percent of the fatalities on South African gold and platinum mines, with associated costs and lost productivity. One of the most important activities in the mitigation of rockfalls is the entry ...Read more
Author:Austin, BADate:2013This report forms a summary of the work done by the Chamber of Mines Research Organization before it merged with the CSIR. It deals with gold mining in South Africa, and contains a summary of the work that was done on underground radio.Read more
Author:Venter, ANDate:Apr 2000The training landscape in South Africa is undergoing veritable metamorphoses as this report is compiled. The Skills Development Bill and its subsequent influence on the National Qualifications Framework (NQF) and the founding of the Mine ...Read more
Author:Stacey, TRDate:Jul 1995Knowledge of the in situ state of stress in a rock mass is essential for the proper planning and design of mine layouts to optimise stability and safety of mining operations. The in situ state of stress in a rock mass can be determined by ...Read more
Author:Hnzido, E; Murray, J; Davison, ADate:Jan 1999The present report describes two additional studies of exposure-response relationship between respiratory disease and silica dust in gold mines. Section 3 describes a study of pulmonary tuberculosis in relation to silica dust, and section 4 ...Read more
Author:De Beer, WDate:Feb 2000This final report on the SIMRAC project GAP409 presents a method (SOOTHSAY) for predicting larger mining induced seismic events in gold mines, as well as a pattern
recognition algorithm (INDICATOR) for characterising the seismic response of ...Read more
