摘　　要：地下矿山在开采作业过程中,由于地质构造及爆破扰动作用,围岩容易失稳,造成片帮冒顶等安全隐患,往往需要采取各种不同类型的支护方式。武山铜矿在地下开挖大断面巷道,遇到松软破碎岩层时,通过采取超前锚杆临时支护,槽钢棚加锚网喷砼联合永久支护的新型方式,既解决了围岩失稳,延长了主要巷道的服务年限,又保证了工期进度,有较为明显的安全经济效益。Because of the geological structure and blasting disturbance, the underground tunnels always tend to roof caving and skiving in underground mining operation. In order to ensure the safety, it should take kinds of different supporting ways. Wushan Copper Mine takes the application of channel steel safe tent and anchor net shotcrete supporting in the face of soft and broken rock to ensure the safety, extends the tunnel length of service, and construction progress, with obvious economic benefits.
