松软膨胀岩层巷道破坏机理及加固技术研究

Study on Tunnel Destruction Mechanism and Reinforcenment Technology in Soft Expansion Rock

松软臌胀岩层的井下巷道支护是目前矿山建设中的一个主要难点。针对霍州煤电集团白龙煤矿的具体条件,对井下巷道的破坏形式及破坏机理进行了分析,在此基础上,提出了合理的修复加固方案。实践表明,应用效果显著。

Underground tunnel support of soft expansion rock is a main difficulty in mine construction currently.Inconnection with the specific conditions of Bailong coal mine of Huozhou coal electricity group,analyses destruction form and mechanism of underground tunnel,on this besis,puts forward reasonable repair and reinforcenment scheme,practice shows application effect is remarkable.
