摘　　要：为了控制深部巷道围岩剧烈变形,分析了桃园煤矿深部矿井巷道支护状况,结合该矿深部巷道第1次支护实际情况,提出巷道二次加强支护设计参数;通过现场监测证明巷道支护状况好转,极大地提高了支护结构的承载能力,从而提高了巷道支护结构的稳定性。In order to control the serious deformation of the surrounding rock in the deep mine roadway, the paper analyzed the support status of the deep mine roadway in Taoyuan Mine. In combined with the first support actual conditions of the deep mine roadway, the pa- per provided the secondary reinforced support design parameters of the mine roadway. With the analysis on the actual operation and the site monitoring and measurements, the results showed that the support conditions of the mine roadway was good which had highly improved the loading capacity of the support system and improved the stability of the support system for the mine roadway.
