注浆与锚索联合支护技术在巷道维修中的应用

Combination Use of Grouting and Anchored Cable In Tunnels Repairing

张集矿部分巷道因受地压和采动影响出现了不同程度的损坏 ,采用传统的支护方式进行修复 ,不但修复工程量大而且效果也不甚理想 ;注浆与锚索联合支护是一种新型的主动支护技术 ,具有施工工艺简单、易操作、适应性强的特点 ,采用根据其机理设计的参数、工艺进行了施工 ,不但较好的解决了巷道维修问题 ,而且还降低了维修成本 ,效果十分显著。

Some tunnels of Zhangji Mine Corporation have been destroyed incoordinately, because of rock thrust and coal mining. Conventional renovated technique has been used to repair them, but result is not good.
