摘要
主要研究"三下"采煤造成的地表变化,进而分析该矿区周边的下沉机理。主要对地表沿工作面开采方向和垂直工作面方向,布设5条观测线,利用天宝的电子水准仪获取外业观测数据,采用沉降观测分析软件和SPSS数据分析软件,分析出变化的曲线,及时对开采的情况进行分析。及时采用"三下"采煤工作面的数据,为开采沉陷、塌陷土地赔偿及综合利用等方面获得了理论科学依据。
This paper mainly studies the surface change caused by"three under"coal mining,and then analyzes the subsidence mechanism around the mining area.Five observation lines are mainly arranged for the surface along the mining direction and the vertical direction of the working face.The field observation data are obtained by using the electronic level of trimble.The change curve is analyzed by using the settlement observation analysis software and SPSS data analysis software,and the mining situation is analyzed in time.The data of"three under"coal mining face adopted in time has obtained theoretical and scientific basis for mining subsidence,land compensation and comprehensive utilization.
