摘　　要：软弱围岩巷道支护质量是煤矿目前面临的重要问题之一,随着开采深度增加,该问题越来越凸显。以杜儿坪矿62515轨道巷为研究对象,首先建立了"锚杆+钢梁+锚索补强"的联合支护体系,通过理论计算结合现场经验确定了具体支护参数,最后通过实地监测得出联合支护的围岩移动量较传统支护下降50%以上,支护效果较好,有很大的应用价值。The quality of roadway support in soft surrounding rock is one of the most important problems of mines. As the mining depth increases, the problem becomes more and more prominent. The 62515 track roadway of Du’erping Mine was taken as the research object, the joint support system of "bolt + steel beam + anchor cable reinforcement"was first established. The specific support parameters were determined through theoretical calculation combined with field experience. Finally, through on-site monitoring, it was concluded that the amount of surrounding rock movement of the combined support was more than 50%, lower than that of the traditional support, and the support effect was good, with great application value.
