摘要
文章以山西霍州辛置煤矿2204工作面为试验研究基地,采用岩石破裂软件RFPA2D模拟开采沉陷过程,研究煤层采动后地表移动及变形的规律;系统地分析了采深采厚比对地表移动及变形的影响。
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 grounxl surface are also discussed in detail.
