摘要：
在新河矿矿井建设过程中，大巷穿越断层带地压显现强烈。利用超前探加固断层加固围岩，大巷采用锚网喷和全封闭式U型钢联合支护一次性通过断层，实现了安全、经济高效地通过断层，并保持断层带巷道的稳定。
关键词: 大巷, 断层破碎带, 主动增强支护, 全封闭U型钢支架
Abstract:
In the process of the construction of the new River mine, the series of the related pressure behaved very strongly when the excavation roadway driving through the faults. The main roadway could one-time excavated the faults zone successfully with the joint support of the bolting and metal mesh, the bolting and shotcreting and the fully enclosed u-steel support, after injecting the slurry into the advanced boreholes to reinforce the self-supporting capability of the surrounding rocks. It had been verified a safe and cost-effective method in the new river colliery and can also maintained the stability of the excavation roadway.
Key words: the main roadway, the fracture zone of faults, the initiative of enhanceing support, the fully enclosed u-steel support
