Abstract: The deformation of rupture rock mass in goaf is the main reason for ground terrene residual deformation. Based on field measurement and similar material simulation, the rupture strata structure and its residual deformation characteristics in the longwall goaf and its overburden are pointed out. On the basis of these achievements, the authors propose the mechanism of strengthening rupture rock mass ground and the control measures of deformation resistant structure. Using the case of main coal building in Xinzhuangzi Coal Processing Plant, this paper introduces the influence of strengthening rupture rock mass and deformation resistant structure.
