Abstract：Land surface subsidence caused by mining may damage buildings，and disaster loss can be reduced by accurate prediction of surface subsidence.The actual geological and surveying data of 21 mining area in Tangdong coal mine were calculated ground deformation of goaf areas with the probability integration method.Overlay analysis of subsidence contour map and topographic map by ArcGIS verifies that probability integration method can accurately forecast ground subsidence.caused bymining.
