为了加强对西部矿区地应力的研究工作,采用了空心包体应力解除法对西部矿区某煤矿进行了地应力测量,初步掌握了该煤矿地应力的分布特征,指出该区的地应力以水平构造应力为主,且均为压应力,而且在同一平面内地应力大小和方向没有发生突变,说明矿区的地应力场比较均匀。
In order to strengthen the research on the geo-stress in western mining area, the hollow encasement stress relieving method was used to measure the geo-stress of a coal mine in the western mining area. The distribution of geo-stress in the coal mine was preliminarily pointed out. Stress, and are all compressive stress, and in the same plane, there is no sudden change in the stress magnitude and direction, indicating that the geostress field in the mining area is relatively uniform.
