摘　　要：针对照金煤矿孤岛范围内的二盘区辅助运输巷受压后急速变形的现状,通过对围岩应力分布、压力显现的基本规律及巷道围岩移矢量分析、论证,利用耦合支护原理,确立了高强度锚索与刚性被动支护相结合的支护设计,解决了高应力动压集中区的巷道维修难题。in view of the rapid deformation of the auxiliary transportation roadway in the second area of Zhaojin Mine,the stress distribution of surrounding rock,the basic law of pressure behavior and the displacement vector of surrounding rock were analyzed and demonstrated.The support design of combining high strength anchor cable with rigid passive support was established based on the principle of coupling support,which effectively solved the problem of roadway maintenance in high stress and dynamic pressure concentration area.
