No. 4 mine deep in Yibei mining area of Xinwen Mining Group Yili, the main recoverable coal seam was covered with unstable roof prone to caving, without thick and hard basic roof, which is a typical shallow buried deep coal seam mining mine. For the study of the mining area land subsidence mechanism and the corresponding parameters of motion, the influence of the theoretical analysis and simulation calculation, the measured data and the theory of displacement back analysis method of combining the shallow buried and deep coal seam large mining height were analyzed to study the mechanism of surface subsidence, it was concluded that the "three zones" observation parameters and static basin, north mining surface subsidence deformation of rock movement parameters, providing the north mining area "three under" mining technical parameters with reference value.
