摘　　要：以晋煤集团圣华煤业3#煤层复采巷道掘进为研究对象,分析研究过破碎冒落区的巷道围岩支护形式,提出以注浆加固围岩为主的"深(浅)孔管棚注浆+对棚+金属网+背板"方案,即采用管棚法构造人工假顶,配合工字钢对棚进行支护,通过管棚对假顶上部松散煤岩体进行水泥注浆永久加固、巷道两侧用背板和金属网加固的支护方案。Based on the Jincheng mining industry group,China coal roadway drivage 3^# coal seam mining as the research object,the analysis has studied broken caving roadway surrounding rock supporting form ,put forward mainly grouting reinforcement of surrounding rock of deep hole （shallow） pipe roof grouting ＋ to shed ＋ metal mesh ＋ back ＂plan,the pipe roof method is used to construct artificial false roof,cooperate with I-steel shed for support ,through the pipe roof cement grouting was carried out on the false of loose coal and rock on the top of the permanent reinforcement, with back and metal mesh reinforcement on both sides of roadway support scheme.
