摘　　要：本次研究针对软岩巷道围岩稳控问题,以实际案例为主要研究对象,首先分析了软岩巷道的基本特点和围岩物理成分测试结果,并在此基础上全面开展了软岩巷道围岩稳控技术的研究工作,为确保矿山安全生产作业奠定了基础。研究显示:受长期矿压的影响,软岩巷道会出现一定的变形,其拱顶位置下沉和两帮凸出现象较为严重,通过全面的力学测试发现,巷道围岩的岩样强度相对较低,需要引入刚柔耦合动态加固技术,以保证其稳定性,应用该技术可以完善围岩的力学性能,保证围岩的完整性,同时也保证了围岩的稳定性,因此对围岩的承载力也能进行有效的提升,然后才能全面提高其稳定性。This study aims to address the stability control issues of soft rock tunnels,with an actual case as the main research subject.Firstly,the basic characteristics of soft rock tunnels and the results of physical composition testing of surrounding rocks were analyzed.Based on this,comprehensive research was conducted on the stability control technology of soft rock tunnel surrounding rocks,laying a foundation for ensuring safe mining production operations.The research shows that due to long-term mining pressure,soft rock tunnels will experience certain deformation,with serious sinking of the arch top position and bulging on both sides.Through comprehensive mechanical testing,it was found that the rock strength of the tunnel surrounding rocks is relatively low and requires the introduction of rigid-flexible coupling dynamic reinforcement technology to ensure its stability.The application of this technology can improve the mechanical properties of the surrounding rocks,ensure their integrity and stability,and effectively enhance their bearing capacity,thus comprehensively improving their stability.
