Seismicity underground with particular reference to rockburst problems

Underground structures such as mine stopes and shafts are continually affected by seismic elastic vibrations. Where these are large and/or sustained they may cause non-elastic motions leading to damage. During the current research program some rockburst mechanisms are highlighted, and applications of active and/or passive mitigation techniques are critically overviewed. Some attempts are made to explain rockburst phenomena in relation to local, mine induced and natural seismicity in Eastern Goldfields of Western Australia. It is emphasised that rockburst research should concentrate on improving the understanding of rockburst mechanisms and the recognition of seismic hazard zones. Advanced monitoring systems are required. New approaches and techniques are briefly discussed.
