充填巷采技术研究及地表变形预测

Study on Filling Roadway Mining Technology and Prediction of Ground Deformation

针对建筑物下压煤开采问题,对充填巷采技术进行了研究,通过材料力学计算得出了巷道开采宽度和留设煤柱宽度,通过概率积分法,对各巷采方案的地表变形预计进行对比分析,从而确定了巷采最优方案。

Aiming at the problem of coal mining under building,the technology of filling roadway is studied.Based on the mechanics of materials, the width of roadway mining width and the width of coal pillar are calculated. By means of probability integral method ,the surface deformation of each plan is analyzed, and the optimal scheme of lane mining is determined.
