摘　　要：以永丰煤业轨道斜巷作为研究对象,在原有支护的基础上,基于现场测试,确定新的支护方式。对于围岩岩性较好且基本无淋水的区段,采用锚网索喷支护;对于围岩破碎但可锚固性能达到要求的区段,采用加强锚网索喷支护;对于围岩破碎、淋水大,顶板岩层可锚固性能达不到要求的区段,仍采用U型钢棚支护。The inclined roadway in Yongfeng coal industry was studied. On the basis of the original support and the field test, the new support was decided. When the surrounding rock is good and basically no shower section, the cable anchor and shotcrete support was used. When the surrounding rock is broken but can meet the requirements of anchoring section, the reinforcing cable anchor and shotcrete support was used. When the fractured surrounding rock, water spray, the roof strata that can be anchorage can not meet the requirements of section, the U type steel shed support was used.
