3D edge detection seismic attributes used to map potential conduits for water and methane in deep gold mines in the Witwatersrand basin, South Africa

Author: Manzi, MSD ; Durrheim, RJ ; Hein, KAA ; King, N Date: Sep 2012 Inrushes of ground water and the ignition of flammable gases pose risks to workers in deep South African gold mines. Large volumes of water may be stored in solution cavities in dolomitic rocks that overlie the Black Reef (BLR) Formation, ... Read more
Developing and exploiting a unique seismic dataset from South African gold mines for source characterization and wave propagation

Author: Julia, J ; Nyblade, AA ; Gok, R ; Walter, WR ; Linzer, LM ; Durrheim, RJ Date: Sep 2008 In this project, the authors are developing and exploiting a unique seismic dataset to address the characteristics of small seismic events and the associated seismic signals observed at local (<200 km) and regional (<2000 km) distances. The ... Read more
Japanese-South African collaboration to mitigate seismic risks in deep gold mines

Author: Ogasawara, H ; Durrheim, RJ ; Nakatani, M ; Yabe, Y ; Milev, A ; Cichowicz, A ; Kawakata, H ; Moriya, H ; JST-JICA SA research group Date: Sep 2009 Mining-induced seismicity poses a hazard to workers in deep South African mines, while natural earthquakes pose a hazard to people living in Japan and other regions of the world that are close to plate boundaries. Researchers introduce a ... Read more
Observational study to mitigate seismic risks in mines: a new Japanese-South African collaborative project

Author: Durrheim, RJ ; Ogasawara, H ; Nakatani, M ; Yabe, Y ; Milev, A ; Cichowicz, A ; Kawakata, H ; Moriya, H ; JST-JICA SA Research Group Date: Sep 2009 Mining-induced earthquakes pose a hazard to workers in deep South African mines, while natural earthquakes pose a hazard to people living close to plate boundaries. Researchers introduce a 5-year Japanese-South African collaborative project ... Read more
Reliable practical technique for in-situ rock stress measurements in deep gold mines.

Author: Stacey, TR Date: Mar 1998 The proposed primary output of this research project is the development of a set of equipment and method of in situ stress measurements in a high stress environment typical of the deep level gold mines. Read more
