... surface monitoring systems in identifying potential instability and the associated failure mode. A challenge for this microseismic application is that many seismic events associated with slope movements are weak and they hardly trigger a microseismic monitoring system that is set up to record an event...

... In this study, the displacement discontinuity boundary element method (DD-BEM) is used to simulate crush- and shear-type failures associated with observed seismic events at two deep South African gold mines: mine X, near Carletonville, and mine Y near Welkom. Crush-type failures associated...

.... A reasonable understanding of what happened is only achieved through a combination of underground observation and seismological analysis. In case 2 the dynamic deformation process is completely different, namely the relatively slow closure of a tunnel associated with one or more seismic events...

... an algorithm that uses the full waveform, including reflected arrivals, to locate a seismic event. The method uses a library of precomputed Green's functions based on a 3D model of the mine tunnels and excavations. The library is used to quickly compute trial waveforms, which are cross-correlated...
