| 摘 要： | 鹤煤五矿延深胶带下山位于向斜轴附近，布置在二1煤层底板中，巷道围岩为砂质泥岩。受地应力、构造应力、采动压力的影响，巷道经过多次维修，围岩极为破碎，曾先后采用锚网喷、强力锚索、高强度网壳、可伸缩U型钢支架等联合支护，也难以控制巷道的强烈变形。经过反复实践，最后采用“双柱腿U36支架+壁后注浆”联合支护方式，支护效果明显改善。

| Abstract: | The downhill belt conveyer roadway was located in Ⅱ1 coal seam floor near the syncline axis，surrounding rock is a sandy mudstone. Influenced by in-situ stress，tectonic stress，mining pressure，and after many times of maintenance repaired，surrounding rock of roadway was very broken. Tested over a variety of supporting methods，such as anchor net spray，high strength anchor cable，anchor truss，U-shaped steel bracket，it was also difficult to control the strong deformation of the roadway. After repeated practice，supporting effect is obviously improved after using the "double legs of 36U-shaped steel + wall post grouting" combined supporting method. |
