摘　　要：为进一步提升对三软煤层回采巷道的支护效果,保证生产安全性,以某矿11011回采巷道为研究对象,在对其顶底板条件进行分析的基础上,对当前支护方案对应的支护现状进行分析;确定了根据巷道冲击性倾向和煤层厚度的柔性支护方案,并通过两帮移近量和顶板下沉量两项指标验证了支护效果。In order to further improve the support effect of the three soft coal seam reclaiming roadway and ensure production safety,the current support scheme was analysed on the basis of the analysis of the top and bottom plate conditions of the 11011 reclaiming roadway as an example,and the support status of the current support scheme was analysed.The effect was verifed by two indicators,namely the amount of displacement of the two helpers and the amount of sinking of the roof.

关 键 词：三软煤层 顶板下沉 两帮移近 巷道围岩控制 U型棚
