摘　　要：针对新安矿区深部极软岩煤巷底鼓、巷道全断面内缩、锚杆(索)拉断、反复修护等现象较为严重的现状,分析了回采巷道破坏特征及原因,提出了采取三心拱拱形断面、拱顶全锚索、两帮"锚杆+锚索"联合支护、综合机械化掘进、增设联络巷等综合措施,施工实践表明基本控制了深部极软岩煤巷围岩变形,为复杂地质条件下煤巷长距离掘进提供了一定的借鉴意义。Aiming at the serious condition of roadway damage in deep coal roadway with extremely soft rock, such as floor heave, full section retraction, anchor （cable） broken, calling for repeated repair, characteristics and causes for the roadway damage were analyzed, countermeasures were proposed including application of three - centered arch section, full cable vault, combined support of the ribs with anchor and cable, fully mechanized driving, additional contact roadway, etc. And construction practice proved the effectiveness of the proposed measures.
