摘　　要：针对淮北矿区破碎围岩巷道出现的变形破坏问题,提出了一种主动支护与被动支护相结合的联合支护方式,分析了该联合支护方式的力学机理、支护条件下的弹塑性。根据现场监测,顶板冒落、帮部脱落、变形严重等问题得到彻底解决,围岩整体稳定性得到显著加强。A combined supporting method of active support and passive support is proposed under the deformation and failures of the broken roof roadway in Huaibei coal mine area. Analyzed the mechanics mechanism and elastic-plastic under the condition of supporting of this combined supporting method. According to the field monitoring, the problem of the tunnel roof collapse, both sides of the roadway fall off and deformation and failures has been solved thoroughly. The overall stability of surrounding rock was enhanced significantly.
