| 摘 要： | 结合综采背拉双工作面回采巷道布置方式,提出3种单段回撤方案,通过对3种方案的技术经济分析比较,得出综采背拉双工作面单段回撤中间巷出设备不施工绞车窝的回撤方式在技术和经济上为最优方案,为类似双工作面布置、停采位置不同单面收尾回撤设备提供借鉴。

| Abstract: | Based on the layout of the mining roadway in the fully-mechanized backhaul double working face，this paper proposes three single-stage withdrawal plans.Through the technical and economic analysis and comparison of the three plans，it is concluded that the single section withdrawal method of the double working face is the best scheme in technology and economy，it can be used for reference for similar double working face layout and different single side closing and withdrawing equipment in stoping position. |
