掘进巷道过断层组支护技术研究

Research on Support Technology of Over Fault Group in a Dug Tunnel

通过分析阶梯状断层组对巷道掘进的影响,采用现场调研和理论分析方法,分析了断层组围岩结构特征,确立了合理有效的支护方案,并进行矿压监测。结果表明,联合支护方案有效地控制了巷道围岩的变形,支护效果较好,可满足安全生产需求。

By analyzing the influence of the stepped fault group on the roadway boring,the structural characteristics of the fault group surrounding rocks were analyzed using field research and theoretical analysis methods,a reasonable and effective support scheme was established,and mine pressure monitoring was carried out.The results show that the joint support scheme effectively controls the deformation of the surrounding rock of the roadway,and the support effect is good,which can meet the demand of safe production.
