Author:Durrheim, RJ; Ogasawara, HDate:May 2012Mining-induced earthquakes pose a risk to workers in deep mines, while natural earthquakes pose a risk to people living close to plate boundaries and even in stable continental regions. A five-year ca. US$3 million Japan-SA collaborative ...Read more
Author:Durrheim, RJDate:Mar 2012Rockbursts pose a significant risk to workers in deep gold and platinum mines in South Africa. In-stope support systems are one of the measures used to mitigate the risk. Over the last two decades several new technologies have been introduced, ...Read more
Author:Yenwong Fai, AS; Durrheim, RJ; Hildyard, MWDate:Sep 2012Mining-induced seismic events pose a serious risk to workers in deep mines. Accurate numerical simulations are useful in analyzing the problem and developing mitigation strategies. Here we tackle the problem of guided interfacial elastic wave ...Read more
Author:Spottiswoode, SM; Roberts, MCKDate:Dec 2001A CSIR team visited the 94E1 panels mining the Carbon Leader Reef in the north-east corner of Tau Tona shaft pillar on the 14th December to study the damage due to a rockburst and to recommend any steps that might reduce the potential for ...Read more
Author:Riemer, KL; Durrheim, RJDate:Jun 2012The Kaapvaal Craton in South Africa hosts one of the largest gold placer deposits in the world. Mining in the Witwatersrand Basin here has been the source of about one third to one half of the gold ever produced in the world. Gold was discovered ...Read more
Author:Share, P; Milev, A; Durrheim, R; Kuijpers, J; Ogasawara, HDate:Sep 2013High resolution tiltmeters were installed during 2007 at Mponeng gold mine, South Africa, in an attempt to study and understand the risks posed by in-mine seismic events and to subsequently use the knowledge gained to mitigate the said risks. ...Read more
Author:Ledwaba, LS; Scheepers, J; Durrheim, RJ; Spottiswoode, SMDate:May 2012Impala Platinum Mine (Impala), situated north of the town of Rustenburg in the North West Province of South Africa, has experienced an increase in seismicity from ~841 seismic events in the year 2005 to ~1588 seismic events in 2008. The ...Read more
Author:Roberts, MKCDate:Dec 1995This 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
