摘　　要：针对同忻矿8105大断面回风巷支护技术难题,本文采用了理论分析对大断面半煤岩巷围岩控制机理以及锚杆-锚索协同支护机理进行了分析,并提出支护方案;通过数值模拟研究了支护方案在巷道掘进时期以及工作面回采期间对围岩稳定性的控制效果,并最终通过现场实测对支护方案进行了验证,结果表明提出的支护方案能够对8105大断面回风巷围岩稳定性进行有效控制,能够满足工作面安全高效的回采要求。In view of the support technology problem of the return air roadway of 8105 large section in tongxin mine,this paper analyzes the control mechanism of the surrounding rock and the mechanism of bolt-anchor joint support by theoretical analysis,and puts forward the support scheme.Supporting schemes is studied through numerical simulation in the roadway construction period and during the mining face control effect on the stability of surrounding rock,and ultimately to support scheme is verified by field testing,the results show that the support scheme is put forward to 8105 large cross-section return air roadway stability under effective control,can satisfy the requirement of the working face safe and efficient mining.
