摘要： 盾构空推通过矿山法段隧道相比其他盾构施工工法技术难度为大, 类似经验缺乏，尤其是在线路曲线复杂、地下水丰富的工程中对施工技术的要求更高。结合盾构空推施工实践，对盾构空推通过矿山法段隧道进行阐述，同时对施工关键部位的质量控制进行了探讨，可为类似情况下的盾构施工提供借鉴。

Abstract: Compared with other shielded tunnel excavation methods, the shielded excavation through empty gullies using mining method is more complicated and no similar construction technique could be followed. The construction becomes more complicated in groundwater rich with complicated tunnel alignments. This paper summarizes the construction procedures of shielded excavation through the empty gullies. Key technical points are discussed in details.
