Abstract
2204 working surface of the Xinzhi mine in the Huozhou of Shanxi are examined in this paper.Numerical methods are used to simulate the mining process,and the movement and deformation of the ground surface after mining are analyzed.Factors such as the incompact stratum depth,mined thickness,the ratio of mined depth are considered and their effects on the movement and deformation of the ground surface are also discussed in detail.
