    Joint Application of Hollow Inclusion Stress Meter and Loose Circle Tester in Coal Mine Surveying

    • 摘要: 煤矿的安全开采十分重要,地应力资料和围岩松动圈的范围是煤矿开采的宝贵地质勘探资料,针对谢桥矿区西翼进风大巷,采用空心包体应力计和BA-Ⅱ型松动圈测试仪对巷道进行地应力测量和围岩松动圈测试。结果表明:该处是以水平应力为主导的高地应力场,巷道的松动圈范围为200~210 cm属大松动圈的Ⅳ-Ⅴ类围岩。针对此地应力场特点提出采用三心拱断面和锚、网、索、注的支护形式。

       

      Abstract: The safety of coal mining is very important. The geo-stress data and the range of loose circle of surrounding rock are valuable geological exploration data of coal mining. In this paper, the hollow inclusion stress meter is used to measure the in-situ stress of the intake roadway in the west wing of Xieqiao Mining Area, and the loose circle test of the roadway is carried out with the BA- II type loose moving coil tester. The results show that the site is in the high geo-stress field and is dominated by the horizontal crustal stress and the loose zone of the roadway is 200 cm to 210 cm, which belongs to the category IV-V surrounding rock. According to the characteristics of stress field in this area, three-core arch section and support form of anchor, mesh, cable and grouting are proposed.
