摘要

为了解决陕西某煤矿浅部和深部地质结构变化较大,导致巷道变形不统一的问题,采用空芯包体应力计对该煤矿巷道围岩进行地应力实测,获取各测点地应力状态,并分析其分布特征。依据地应力测试结果,对原有支护方案进行了优化。
        In order to solve the problem of disunity of roadway deformation in a certain coal mine in Shaanxi province, whose geologic structure is rather changeable in shallow and deep areas,the hollow inclusion gauge was applied to measure the ground stress in the roadway surrounding rock in the coal mine to detect stress state and to analyze distribution characteristics of each measuring point. According to the measured results of ground stress, an optimization was conducted on the previous support plan.
