大断面切眼通过复合断层锚杆支护的新方法

The New Method of the Bolt Support through the Compound Fault of the Cut-hole with the Large Cross-section

古书院矿91306工作面切眼大断面巷,在施工中遇到二组复合断层,采用锚杆挂网加钢带联合支护的方法,顺利通过了大断面复合断层破碎带,取得了良好的效果,为今后推广大断面巷过断层破碎带采用锚杆支护提供了经验。

In the construction of 91306 face＇s cut-hole with the large cross-section in Gushuyuan Coal Mine there are two groups of compound faults, adopting the method of the joint support of the bolt suspended net and steel band obtains good results of passing through the fracture zone of the compound fault with then large cross-section, which provides experiences for popularizing this method.
