摘要
Abstract
In response to the problems of poor stability of surrounding rock in fault fracture zones and low efficiency of traditional support,a technical system of"dynamic support of airborne front beam+coordinated control of yielding anchor cables"is proposed based on the engineering background of the 5311 transportation channel crossing the FZ8 fault zone in Zhaolou Coal Mine.By optimizing the spatiotemporal coordination mechanism of support,temporary support can be completed within 5 minutes after excavation,resulting in a 62.1%reduction in roof separation and a 77.6%decrease in anchor cable breakage rate compared to traditional methods.On site application has shown that this technology improves daily excavation efficiency by 41.5%,reduces comprehensive costs by 13.3%,and reduces accident rates by 86.5%,providing a replicable solution for tunnel support under complex geological conditions.关键词
