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 problems of coal mining under building pressure, the technology of filling roadway is researched. The mining width of coal roadway and the width of coal pillar are obtained through the calculation of material mechanics. Probability integral method is used to predict the surface deformation of each roadway. Comparative analysis, which determines the optimal mining project.
