摘  要:针对综放面大断面煤巷掘进速度慢的问题,采用“一次让压+二次补强”支护方案。经过验证,空顶距为3.2m、二次补强支护滞后距离为12.8m时,巷道稳定性和掘进效率显著提升,新的支护方案使得掘进效率提高了约60%。In response to the slow excavation speed of large-section coal roadways in fully mechanized top coal mining,a support scheme of"one-time yielding+secondary reinforcement"was adopted.After verification,the stability and excavation efficiency of the roadway were significantly improved when the unsupported roof distance was 3.2 m and the lag distance of the secondary reinforcement support was 12.8 m.The new support scheme increased the excavation efficiency by about 60%.
