摘　　要：应用组合梁和悬吊理论,对松软岩层采用支护新技术,即锚、网、带、索、喷等联合支护方式,加强对松软岩层巷道顶板的控制,降低了材料支护费用,提高了软岩巷道支护的可靠性,同时也提高了松软岩巷的掘进速度。This paper described the practice of using combined beam theory and suspensory theory, such as roof bolt, net, steel rope, and shotcrete being used together to strenthen roof control. The cost of supporting materials are reduced, supporting stability is improved, and development is speed up in soft rock road.
