Pusa collapse is a typical example of the deformation and failure of the antidip slope Mining activities aggravate the deformation of the overlying rock mass which makes the cracks further expand and leads to the instability of the upper slope The failure factors of landslides are closely related to the unique geological conditions of slopes
bedding rock slope slip body after the mining of the lower and upper coal seams were simulated According to the geological and mining technical conditions of the coal mine it can be seen that except for the buried depth the parameters of the upper and lower coal seams were basically the same Therefore in the numerical simulation
