| 摘 要： | 六苴铜矿深部开采过程中面临着较大的高应力灾害问题，在综合对比分析目前国内外主要地应力测量方法的基础上，确定采用空心包体应力解除法进行矿区地应力测量。本次地应力测试工作共布置了4个测点，每个测点进行了两次应力解除测量，大大的提高了测试结果的精度。测试分析得到了岩体最大主应力值、应力方向以及深部岩体的应力分布规律，可为后续深部巷道布置、支护设计优化等工作提供可靠的基础参数。

| Abstract: | The deep mining in the Liuzuo copper mine can potentially trigger disasters caused by high stress. After comprehensive comparsion of the main methods for stress evaluation, the hollow inclusion gauge method is selected to measure the ground stress. Four measuring points are deployed and each point is measured twice to improve the accuracy of the test. The results of the analysis include the value of the maximum principal stress, the orientation of the major principal and the distribution of the deep rock mass stress. These data can provide reliable parameters for the deep roadway layout and the optimization of support design. |

| Keywords: | ground stress stress relief hollow inclusion gauge deep rock mass |
