深井软岩巷道底臌治理锚注联合加固技术研究

Research of the Anchor Joint Reinforcement Technique of Treatment of Floor Heave in Soft Rock Roadway

针对朱集西矿副井南等候硐室出现严重底臌问题,综合采用工程地质调研、数值模拟方案分析、工程类比设计施工方案的方法,制定实施了底臌治理锚注联合支护加固技术。结果表明:两帮的最终位移量为35mm,顶底板的位移量为30mm,满足生产的要求,为类似工程提供参考。

According to the severe floor heave problem of ZhuJi coal mine South auxiliary shaft waiting chamber, using the method of comprehensive engineering geological investigation and numerical simulation analysis and engineering analogy to design the construction plan, the formulate and bolting and grouting combined supporting reinforcement technology. The results show that the final displacement of the two sides is 35mm, and the displacement of the roof and floor is 30mm, which meets the requirements of production and provides reference for similar projects.
