东滩煤矿3306工作面开采地表移动变形规律分析

工作面开采时,为了解工作面上方区域地质采矿条件下地表移动变形状况,通过建立地表移动观测站的方式获得观测数据,并通过数据进行分析计算地表移动范围大小和位置的参数以及地表动态移动与变形的参数;根据实测下沉值,拟合下沉系数、水平移动系数等进行预计、分析,研究地表最终移动与变形值的大小及分布规律。

Analysis of surface movement and deformation law of mining in 3306 working face of Dongtan coal mine

In order to understand the surface movement and deformation in the area above the working face under geological mining conditions,observation data are obtained by establishing a surface movement observation station,and the parameters of the surface movement range and position and the parameters of the surface dynamic movement and deformation are analyzed and calculated through the data.According to the measured subsidence value,fitting subsidence coefficient,horizontal movement coefficient,etc.,predict and analyze,and study the size and distribution law of the final surface movement and deformation value.
