摘　　要：对城峰煤业100501工作面预掘单回撤通道进行了掩护式支架支护的实践研究,利用井下闲置的ZY6800/23/47型支架,构建了“锚+索+网联合支护”+“掩护式液压支架”新型耦合回撤巷道支护方式。实践结果表明:巷道顶底板及两帮表面最大移近量较小,巷道围岩稳定性好,工作面回撤工期缩短25 d,创造经济效益约100万元。A practical study of cover type bracket support was carried out for 100501 working face pre-digging single retraction channel of Chengfeng Coal Industry.Using the idle ZY6800/23/47 stent,a new type of coupled retraction roadway support method of"anchor+rope+net joint support"+"cover hydraulic stent"was constructed.The results show that:the maximum approaching amount of the top and bottom plates and the two gang surfaces of the roadway is smal,the stability of the roadway perimeter rock is good,and the retracement period of the working face is shortened by 25 d,which creates an economic benefit of about 1 million yuan.
