摘　　要：煤矿深部开采巷道与浅部巷道的主要差别是围岩存在破裂区,也是深部巷道支护的重点之一。由于破裂区的存在,巷道支护应以护为主,防止围岩破裂范围扩大,巷道失效。提出了深部巷道支护的7大设计原则。理论与实践证明巷道底角采用弧形,加强巷道底角与肩部等关键部位的支护强度,使巷道整体收缩变形,可有效防止深部巷道的破坏。The main difference of deep mining roadway from shallow roadway is exist of cracked area in surrounding rock of deep roadway which is one of the key supporting areas. Because of cracked area, roadway supporting should be give priority to ＂ support＂ for preventing cracked area from expanding and roadway instability. This paper put forward 7 design principles for deep roadway supporting. Theory and practice showed that making roadway whole in shrinking deformation might prevent deep roadway instability by applying arc base angle and increasing supporting intensity at roadway base corner and roadway shoulder.
