肖家洼煤矿110801工作面地表移动变形规律研究

Study on surface movement and deformation of 110801 working face in Xiaojiawa coal mine

文中利用山西肖家洼煤矿110801工作面地表观测站实测数据,探讨了厚黄土层薄基岩开采条件下地表移动变形规律,获得该地质采矿条件下概率积分法的各项参数,以及各移动变形角量参数。研究了采用概率积分法理论进行曲线拟合法时的修正方法。探讨了山体滑移对山谷监测点的影响规律。

Based on the measured data of surface observation station of 110801 working face in Xiaojiawa coal mine in Shanxi, this paper discusses the law of surface movement and deformation under the condition of thin bedrock lay- er mining of thick loess layer. The parameters of probability integral method in the condition of the geological mining are obtained. The correction method of the curve fitting method is studied by using the probability integral method. The influence of mountain slip on Valley monitoring points is also discussed.
