In orderto analyze and evaluate the residual deformation of longwall goaf and its effect on new buildings, the stability of building foundation above the old longwall goaf was studied using the FLAC3D software. According to the results of probability integral method, the mechanical parameters of the geologic body were solved by inversion analysis. The subsidence deformation of building foundation above longwall goaf under the ground building loads and vertical stress were calculated by numerical simulation. By comparing the deformation of building foundation above longwall goaf before and after grouting and building, the stability of building foundation above longwall goaf and the security of the building were evaluated.
