摘　　要：为了探讨松软破碎围岩巷道合理的控制方法,通过现场调查、实验室实验和理论分析及数值计算方法,对吉林桦甸油页岩矿支护现状进行分析,总结破坏原因。并针对其破坏特点,提出了以自钻注浆锚杆为核心,锚网喷+全封闭U型钢可缩性金属支架耦合支护技术。工程实践表明:采用自钻注浆锚杆为核心的耦合支护结构,有效地解决了松软破碎围岩巷道的支护问题。For the purpose of exploring the reasonable method controlling loose,soft and cracked wall rock tunnel,by field investigations,experiments in laboratory,theoretical analysis and numerical calculations,observed and analysized the local supports of oil shale mine in Huadian,Jilin Province,and summarized the reasons why them were destroyed.In view of the characteristics,a support method,self-injected anchor as its core,anhor,wire netting,injection concrete mortar and retractable U section steel support coupling,was presented.Engineering practice indicates that the support problem for loose,soft and cracked wall rock tunnel can be solved effectively by using the above coupling support system with self-injected anchor as its core.
