  • Kgarume, T; Milev, A; Nakatani, M; Naoi, M; Yabe, Y; Philipp, J; Durrheim, RJ; Ogasawara, H; Ward, T (South African Geophysical Association, 2013-10)
    The dependency of the quality factor derived from S wave coda (Q(subc)) on frequency is analysed in order to understand the effect of fracturing ahead of a mining stope. Micro seismic events recorded using acoustic emission ...
  • Durrheim, RJ; Ogasawara, H; Nakatani, M; Yabe, Y; Kawakata, H; Naoi, M; Ward, AK; Murphy, SK; Wienand, J; Lenegan, P; Milev, AM; Murakami, O; Yoshimitsu, N; Kgarume, T; Cichowicz, A (Australian Centre for Geomechanics, 2012-03)
    Mining-induced earthquakes pose a risk to workers in deep mines, while natural earthquakes pose a risk to everywhere, but especially near plate boundaries. A five year Japanese–South African collaborative project entitled ...
  • Naoi, M; Nakatani, M; Horiuchi, S; Yabe; Philipp, J; Kgarume, T; Morema, G; Khambule, S; Masakele, T; Ribeiro, L; Miyakawa, K; Watanabe, A; Otsuki, K; Moriya, H; Murakami, O; Kawakata, H; Yoshimitsu, N; Ward, A; Durrheim, R; Ogasawara, H (Springer Basel, 2014-10)
    The authors investigated frequency-magnitude distribution (FMD) of acoustic emissions (AE) occurring near an active mining front in a South African gold mine, using a catalog developed from an AE network, which is capable ...
  • Ogasawara, H; Hofmann, G; Kato, H; Nakatani, M; Moriya, H; Naoi, M; Yabe, Y; Durrheim, R; Cichowicz, A; Kgarume, T; Milev, A; Murakam, O; Satoh, T; Kawakata, H (AIST, 2013-09)
    The Japanese-South African intergovernmental science and technology project “Observational studies to mitigate seismic risks in mines” includes seismological studies aimed at a better understanding of how a seismic event ...
  • Kgarume, T (University of the Witwatersrand, 2010-11)
    A methodology of assessing the seismic hazard associated with aftershocks is developed by performing statistical and deterministic analysis of seismic data from two South African deep-level gold mines. A method employing ...

    Mining-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 5-year Japan-SA collaborative ...

    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 ...
