Abstract : Within the Provence opération Unit France, microseismic remote monitoring is integrated within a research strategy bearing on areas submitted to dynamic phenomena risks. The purpose of this study is to characterise and analyse the induced microseismic activity during the opération of deep sites, in order to obtain identification criteria for the zones likely to generate such phenomena. The detailed study of the space distribution of microseismic focuses enables consistent corrélations to be demonstrated between the localization of the focuses, the changes in the state of stresses in the massif during the mining opération and the configuration of exploitation. The results hâve opened interesting perspectives into the analysis of pressure rockburst risks, by microseismic listening.
