Abstract
Summary
In this study, the displacement-discontinuity boundary-element method is used to simulate large-magnitude, slip-type failures associated major geological structures in an ultra-deep, South African gold mine. The above-mentioned slip-type failures are simulated using a so-called RIDE algorithm, and the modelled seismic response is described in terms of the expected number of seismic events with some potentially-damaging size. In this case, the modelling results are well correlated with the observed seismic response.
