Méthodes de prévision des dégradations des structures bâties en zone d'affaissement minier

Abstract : Mines and underground quarries, exploited or abandoned, can lead to ground subsidence. Whatever their origin, accident or well-known consequences of actual exploitation, they induce important permanent displacements of the ground surface which can damage buildings. Management of urbanised areas which are concerned, deals with damage criteria and remedying propositions. This paper is about different kinds of methods for building damage prevision from different countries and with different criteria related to the ground, the subsidence and structures. Theses methods are compared with one another and with reality. A statistical study was performed with mining subsidence which occurred in iron mining basin in Lorraine (France) for 1996 to 1999. With almost 400 observations, it shows high correlations between damage level and some characteristic parameters of subsidence or structures. It is then possible to elaborate a method for damage level and risk estimation useful for the iron mining basin in Lorraine.
