　　为研究煤矿深部原岩应力对巷道围岩破裂范围的影响规律，采用空心包体法在郓城千米埋深煤矿井底车场进行地应力实测，得到了煤矿深部原岩应力状态，并应用声波测试方法，测量得到了不同巷道帮部的围岩破裂范围。将原岩应力转化为与巷道帮部直墙面平行截面上的初始径向应力和初始剪切应力，研究不同初始应力状态下巷道围岩破裂范围发现：初始径向应力对深部围岩破裂范围影响较为显著，且初始径向应力越大破裂范围就越小；而初始剪切应力对围岩破裂范围的影响显著性较小。此外，实测结果还证实了围岩岩性和巷道断面大小是影响围岩破裂范围的重要因素。

In order to study the influence law of deep underground in-situ stress on the size of failure zone in surrounding rocks of mining roadway,an in-situ stress measurement was conducted under Yuncheng one kilometer-depth mine by means of hollow inclusion gauge method, and the in-situ stress state around the shaft station was obtained. Then the sizes of surrounding rocks’ failure zone in the walls of different roadways were measured with acoustic wave. The in-situ stress was transferred into initial radial stress and initial shearing stress on the vertical walls’ parallel sections. Through comparing the sizes of failure zones under different initial stress state, it was discovered that the influences of initial radial stress on failure zone in surrounding rocks were remarkable and the range of failure zones would be smaller with higher initial radial stress. Nevertheless, the influences of initial shearing stress were much less obvious. Besides, the measuring results also confirmed that the property of surrounding rocks and the size of roadway section were significant factors influencing the dimensions of failure zone.
