摘　　要：针对东峰煤矿3号煤层工作面顺槽过度支护问题,采用相似模拟实验、数值模拟和工程试验等方法,对支护方案进行了研究,确定了单排锚索偏心布置的锚杆锚索联合支护的优化方案。该方案节省了工程量和成本,提高了效率和效益。这对完善支护设计理论和进行支护改革实践具有重要的现实意义。In view of the over-support problem of mining roadway in No. 3 coal seam in Dongfeng Coal Mine,by using the similar simulation experiment,numerical simulation and engineering test,the support scheme was optimized,and the bolt and cable combined support scheme of the eccentric arrangement of single row anchor cable was proposed. The scheme saves engineering quantity and cost as well as improves efficiency and benefit. The study has great practical significance to improve the support design theory and supporting reform practice.
