摘　　要：地下工程掘进过程中经常会遇到不同程度的垮塌冒落现象,望儿山金矿在其深部工程施工中,采用型钢冷拔钢丝与喷射混凝土相结合,辅之以壁后注浆工艺,对3处巷道冒落地段进行了永久支护,不但有效地解决了不良地层的掘进冒落问题,而且对地下水的防治也起到了良好的效果。In the tunneling process of underground engineering, usually there are different kinds of collapse. In the deep underground excavation of Wang＇ ershan gold mine, three sections of instable laneway with roof fall damage were supported by section steel-net-sprayed concrete system and injection in the wall-rock. As a result, the roof fall problem was solved and moreover the underground water was controlled effectively.
