Abstract：Part of the S5-12 working face in Wangzhuang coal mine is located in the village's protective coal pillar. To realize visualization of surface subsidence deformation after part of filling mining, partial filling mining surface subsidence deformation prediction method is established by using the probability integral method, distance power inverse ratio method and the contour-map method of rectangular grid model. By establishing the prediction method calculate the mining thickness within the coal pillar in the safety of the surface building is 3. 5 m. The equivalent mining model is applied to backstep the gangue minimum filling height is 4. 03 m.
