结合西（安）南（京）铁路桃花铺2#隧道施工实践，介绍和探讨单线长大铁路隧道钻爆法开挖机械设备选型与配套技术，洞内轨道布置及调车作业、洞口车辆布置等施工组织情况。得出机械设备的选型与配套技术是关系长大隧道施工成败的最主要因素的结论。本隧道实现的快速掘进对今后的隧道施工具有借鉴意义。

Taking the construction of No. 2 Taohuapu tunnel on Xi'anNanjing railway as example, the article describes the technology of type selection and matching of machinery for the drill+blast construction of long single track railway tunnels, the layout of the track system and the dispatching of the locomotives and wagons inside the tunnel and the organization of the locomotives and wagons in portal portion of the tunnel. The article concludes that the type selection and matching of the construction machinery is one of the most critical factors that determine the success of the construction of long tunnels. The rapid driving of the tunnel will provide reference for similar tunnel works in the future.
