Abstract: This paper, through establishing a numerical simulation model, studied the damage mechanism of the overlying strata and the movement and deformation value of the ground subsidence and horizontal deformation induced by strip mining below thin bedrocks. The movement and deformation laws of the stress and displacement fields of the overburdening strata and ground are demonstrated. The conclusions provide a basis for the further research on the engineering geological mechanism of the overlying strata and ground movement and deformation induced by strip mining below thin bedrocks.
