摘要
分析了1304工作面回风巷破坏机理,结合现场情况决定采用"锚网索喷"对该巷道部分区段进行修复和加固。结果表明,通过该方案的实施,有效控制了巷道变形和破坏,支护效果较好。
This paper analyzed failure mechanism of return air roadway in the 1304 working face, adopted ＂combined support with bolt wire cable and shotcrete＂ to repair and reinforce some sections of roadway combined with field condition. The results showed that the implementation of scheme can effectively control the deformation and destruction of roadway and have good supporting effect.
