In Jinchuan Mining District, with the engineering geological condition being very complex, the rock mass being seriously soft and fractured, and the ground stress being high, nearly 25 percent of roadways are in weak rock mass, the support of roadways is a serious problem. The authors have made a detailed investigation on the deformation and failure laws of the roadway in weak rock mass in Jinchuan mine, systemically evaluate the support effect of all kinds of support way used in this mine, and introduce the bolt-shotcrete-mesh support, grouting reinforcement support as well as combined support in detail, finally summarize the optimal support way for all kinds of roadways in similar highly stressed weak rock mass according to many years of in-situ experience.
