摘　　要：着重阐述了大断面岩巷掘进支护中如何解决大跨度断面硐室支护选型,锚网喷中铁丝网不抗强压,锚网喷二维受压的不稳定性,因硐室断面积大不能一次成巷的问题,同时在硐室断面合理分台阶和布置炮眼,提高掘进速度。科学实用,效果显著。Focuses on a large section of rock roadway excavation pit in how to solve the large span cross section chamber pit selection,with wire mesh of barbed wire are not sprayed anti-forced,twodimensional wire mesh spray pressure instability,due to broken chamber can not be a large area into the issue of lane,at the same time in the chamber at a reasonable cross-section embrasure steps and arrangements to improve the driving speed.Scientific and practical,results are obvious.

关 键 词：硐室 锚网喷 高强锚杆
