Simulation numérique 3D du foudroyage d’une exploitation par panneaux à grande échelle

Abstract : The simulation of the goaf area associated with panels is essential in large scale mines. In this study, the goaf area is simulated by using elastic numerical modelling, to assess the stress and displacement field changes in a Provence coalmine with taking into account the goaf geometry and its equivalent mechanical properties. The evolution in space and in time Heterogeneity of the goaf material is simulated by using linearly varying elastic modulus, which has been calibrated with the surface subsidence measurements.
