Amélioration de la prévision des affaissements dans les mines à l'aide des approches empiriques, numériques et analytiques

Abstract : The surface movements due to underground mining (phenomenon of mining subsidence) are of very complex nature. The resulting damage on surface infrastructures varies according to the magnitude of these movements. The "Unité d'Exploitation Provence" of the "Houillères de Bassin du Centre et du Midi" (UEPHBCM), in France, uses an empirical method based on the NCB abacuses for the ground movements prediction. But, this method is limited to simple geological characteristics and to ruined areas of rectangular shapes. Thus, we propose and validate on various mines a new methodology of subsidence prediction. It results from a synthesis of analytical and empirical concepts, and data resulting from numerical_ modeling in two or three dimensions. The methodology takes into account the complex character of the mining subsidence phenomenon.
