摘　　要：通过对芦岭煤矿Ⅱ82轨道上山实施围岩单一支护的对比分析,提出了一种全新的高强稳定型耦合支护技术。该技术使单一支护的尖顶、平顶、底鼓等破坏形式消失。实践证明,该技术在充分发挥各类单一支护优势的同时能起到协同支护的效果,控制巷道围岩变形效果显著。Through the contrastive analyzing of several single shoring in surrounding rocks of Ⅱ 82 up-tunnel in Luling Coal Mine, a new high strength and steady coupling shoring technology is put forward. The technology makes the destructive formats such as tine-shaped coping, flat-shaped coping and plump footwall disappear. It is testified by practice that the technology can control deformation of surrounding rocks obviously because it can contribute on cooperative shoring when exerting predominance of several single shoring.
