Spatial Distribution of Mining Tremors and the Relationship to Rockburst Hazard

Within the Provence colliery (France), seismic remote monitoring is integrated in a research strategy on areas subject to rockburst. The purpose of this study is to characterise and analyse the induced microseismic events during the mining operations, in order to identify or establish criteria for the zones likely to generate rockburst. The detailed study of the space distribution of microseismic events enables consistent correlations to be demonstrated between the location of events, the changes in the state of stress in the massif during the mining operations and the configuration of exploitation. The results have opened interesting perspectives into the analysis of the spatial distribution of mining tremors and their relations to rockburst hazard.
