随着嵩山煤矿2204综采工作面的推进,即将推进至赵城水库附近下部,有可能对赵城水库附近农田及其他设施产生影响。因此,必须加强对赵城附近区域进行地表岩移沉降进行实时观测。本文,笔者依据在赵城区域设置不同的沉降观测点,结合下沉活跃情况按周期进行沉降观测,采取了计算比较相对高差位移的方法。一、2204工作面地质采矿条件2204工作面北临2202工作面采空区,东部、西部及北部皆无采动影响,无村庄保护煤柱。本煤田可采煤层为二1煤层,
With the advancing of 2204 fully mechanized coal mining face of Songshan Coal Mine, it is about to advance to the lower part near Zhaocheng Reservoir, which may affect the farmland and other facilities near Zhaocheng Reservoir. Therefore, it is necessary to strengthen the real-time observation of the surface rock mass settlement in the area near Zhaocheng. In this paper, based on the different subsidence observation points in Zhaocheng area and the subsidence observation in the light of the subsidence activity, a method of calculating and comparing relative elevation displacements is taken. 2204 Face Geological Mining Conditions 2204 Face 2202 Face north of the work area, eastern, western and northern mining no effect, no protection of coal pillars in the village. The coal mine can be two coal seams,
