| Abstract: | Taking goaf of a lead-zinc mine as a background a 3D model is established. By the way of theoretical analysis and numerical simulation, this paper analyzes displacement and stress of rock. Research results gain features of displacement stress distribution and plastic failure, and also advance goafStreatment measures, that provides references for stability assessment and treatment measures of goaf. |
