摘要： 针对顺和煤矿-702m水平轨道运输巷道穿煤层地段围岩破碎、地应力大、工程条件差等支护难题，在分析了原支护方案的不足及巷道围岩变形破坏特征的基础上，结合巷道围岩的实际赋存情况，提出了“锚-网-索-喷-注-棚”的控制方案，矿压观测表明：支护方案效果明显，围岩得到了有效的控制，支护效果良好。

Abstract: according to -702m for horizontal rail haulage wear seams Lot: rock crushing, to stress, work conditions and poor support problems, the analysis of the original support programs and the lack of surrounding rock deformation and failure characteristics based on the combination roadway actual occurrence situation, put forward the "anchor - Network - cable - spray - Note - shed" control scheme, pressure observation showed that: support Schemes effect is obvious, rock has been effectively controlled, supporting effect good research on the broken rock, unstable rock roadway project with a reference value.
Key words: deep, crushing rock, through Coalbed, roadway support, industrial test
