Abstract: The deformation and damage of goaf landslide induced by underground mining, taking a goaf landslide as an example, using finite element method, we explore the mechanical characteristics of goaf and the deformation process of goaf landslide. The results show that the deformation of the gob destruction gradually formed under the action of four main stress, and produced four kinds of stress concentration area, high tensile stress, high compressive stress, high shear stress clusters, high ballooning stress. At the same time, by comparing the landslide displacement, stress and strain before and after the excavation, we deduced the slope deformation process: the coal seam mining, trailing edge cracking, middle sagging, leading edge shearing and landslide.
