摘　　要：针对马兰矿10106工作面运输巷围岩变形破坏严重、采掘过程中围岩容易垮落、锚杆失效等问题,结合该工作面的工程地质条件,采用数值模拟与现场实践相结合的方法,探究锚杆索等支护参数对巷道围岩变形的影响,确定了锚杆索联合支护技术方案,取得了显著效果。In view of the serious deformation and damage of the surrounding rock of the transportation roadway in the 10106 working face of Malan Coal Mine, the surrounding rock is easy to collapse and the anchor bolt is easy to fail during the mining process, combined with the engineering geological conditions of the working face, the method of combining numerical simulation with underground practice is adopted to explore the influence of the support parameters such as anchor bolt and cable on the deformation of the surrounding rock of the roadway, and the technical scheme of combined support of anchor bolt and cable is determined, which has achieved remarkable results.
