Identification des mécanismes de rupture des évènements microsismiques induits par une exploitation minière : approche méthodologique

Abstract : The Gardanne coalmine, is accompanied by an important seismic activity : 50 to 80 microseisms per day, inducing sometime dangerous rockbursts. The microseismic registering that was placed 1977, is aimed at forecasting and prevention. Based on classical seismograms analysis, a methodology is developed with this database. It consists of demonstration of the existence of different types of mechanisms, and their identification. This methodology allows the identification ofshear-fracture, the rupture of rock behind the face and complex mechanisms for with numerical models where necessary. We although observe that events associated with different mechanisms have different spectral analysis. But it was not possible to define simple discrimination types.
