No. 14 and No. 15 coal seam is high and low seam in Yongdingzhuang Mine of Datong Mining Group, the corresponding surface of the two coal seam is village buildings, which affected the surface after mining. In order to know the movement of surface basin of the two seam after mining, the maximum deformation of the plan was designed, the surface movement was predicted by probability integral method. The prediction result showed that the maximum surface sinking is 950 mm, sinking basin without the sufficient mining, the range influence of surface sinking basin is 8.9 times than the goaf, due to the large mining depth, with small mining area, the surface deformation belongs to the normal range, which did not affect the safe mining.
