Effondrement et affaissement des mines de fer en Lorraine : rôle de la couverture et de la morphologie

Abstract : The events which have occurred in the lorrain iron basin during this last decade came to underline problems generated by mining industrial cessation and concession surrender like people or goods security. In this study, we studied the role which can play the geomorphology on the mechanical behaviour of overburden in relation with the violent collapse and progressive subsidence phenomena. We have examined valley and tray situations with the presence of vertical fractures and postponed valley situation through 2D (UDEC) and 3D (FLAC3D) modelling. Next, we simulated the fracture development in a mine pillar through a continue (FLAC) and discontinue (PFC) approach. These numerical modellings allow to apprehend the overburden role in a concern for hazard zone control
