Abstract Due to the movement of overlying strata after working face mining, which would cause influence on the deformation of the surface, for further study 1110204 working face mining surface deformation, the probability integral method of ground deformation was expected. According to the geological and mining conditions, the surface deformationwas expected to need each estimated parameter, expected results were visualized, surface sink value, value tilt, curvature value, value of horizontal movement and deformation value were analyzed. The results showed that the maximum subsidence value was 2 500 mm, the slope value was 16 mm/m, the curvature value was 0.16 × 10-3/m, the horizontal moving value was 850 mm and the horizontal deformation value was 8 mm/m.
