Author: Ogasawara, H ; Nakatani, T ; Durrheim, RJ ; Naoi, M ; Yabe, Y ; Moriya, H ; Hofmann, GF ; Stander, C ; Roberts, David P ; De Bruin, P ; Oelofse, J ; Kato, H ; Cichowicz, A ; Birch, D ; Ngobeni, D ; Milev, A ; Kgarume, Thabang E ; Satoh, T ; Horiuchi, S ; Kawakata, H ; Murakami, O ; Yoshimitsu, N ; Ward, AK ; Wienand, J ; Lenegan, P ; Yilmaz, H ; Mngadi, S ; Piper, PS ; Clements, TN ; Nakao, S ; Okubo, M ; Ishii, H ; Visser, AV Date: Sep 2014 A multi-disciplinary study of the response of the rock mass to mining and mining-induced earthquakes has been conducted in six gold mines in South Africa at sites deeper than 3 km, or with equivalent stress. More than 80 holes (with a total ... 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
Relating high-resolution tilt measurements to the source displacement of an M2.2 event located at Mponeng gold mine

Author: Share, P ; Milev, A ; Durrheim, R ; Kuijpers, J ; Ogasawara, H Date: Oct 2013 As part of JAGUARS (JApanese-German Underground Acoustic emission Research in South Africa), high-resolution tiltmeters were installed during 2007 at Mponeng gold mine, South Africa, in an attempt to study and understand the risks posed by ...

Relating tilt measurements recorded at Mponeng Gold Mine, South Africa to the rupture of an M 2.2 event

Author: Share, P ; Milev, A ; Durrheim, R ; Kuijpers, J ; Ogasawara, H Date: Sep 2013 High 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. ...

Relationship between ERR and seismic energy release for different geotechnical areas.

Author: Spottiswoode, S ; Napier, J ; Milev, A ; Vieira, F Date: Apr 2000 This report describes a re-analysis of previous work on the relationship between ERR and seismicity. Data from four mines spanning the Ventersdorp Contact, Carbon Leader and Vaal Reefs were analysed using the MINF suite of programs (e.g. ... Read more
Seismic moment tensor resolution on a local scale: Simulated rockburst and mine-induced seismic events in the Kopanang gold mine, South Africa

Author: Sileny, J ; Milev, A Date: Aug 2006 Seismic records contain information about the effect of the source as well as the effect of wave propagation through the rock mass. The effect of wave propagation is usually not well known as only simplified models of geological structures ... Read more
