摘　　要：针对长平煤矿53051巷掘进期间受F2断层影响,巷道掘进期间出现顶板破碎现象,为了进一步提高掘进巷道顶板稳定性,分析了原顶板支护在断层带处主要存在的问题,并根据实际生产情况对原支护进行优化,提出了密集矩形工字钢棚支护,通过实际应用效果来看,密集工字钢棚提高了破碎带顶板整体稳定性,削弱了顶板垂直应力对顶板破坏作用,取得了显著应用成效。In view of the influence of F2 fault during the driving of 53051 roadway in Changping Coal Mine,the phenomenon of roof breakage occurs during the driving.In order to further improve the stability of the driving roadway roof,this paper analyzes the main problems of the original roof support in the fault zone,optimizes the original support according to the actual production situation,and puts forward the dense rectangular I-shaped steel shed support,Through the practical application effect,the dense I-shaped steel shed improves the overall stability of the roof in the broken zone,weakens the damage effect of the vertical stress of the roof on the roof,and achieves remarkable application effect.
