摘　　要：为解决杨河煤业高应力软岩巷道的支护问题,对杨河煤业深部软沿巷道变形破坏特征及原因进行分析,提出支架-锚杆-围岩卸压耦合支护技术,并结合42轨道下山试验巷道对耦合卸压支护技术参数进行阐述,通过矿压观测结果可知:42轨道下山在采用卸压耦合支护技术后,有效控制了巷道强烈变形。To solve the support problem of high-stress soft rock roadway in Yanghe Coal Mine,the failure characteristics and reasons of soft rock roadway are analyzed,the technology＂support-anchor bolt-rock surrounding relief pressure coupling support＂is put forward and the technical parameters of coupling support are stated by the support of experimental tunnel in 42 track dip. Known from the pressure observation,the roadway deformation can be effectively controlled after adopting pressure relief and coupling support.
