本文以山西晋煤集团岳城矿1302（下）综采工作面为例，探讨了U型通风系统工作面采空区瓦斯涌出规律及其治理原则，研究结果表明，通过在回风巷敷设两趟采空区管路，一趟插入上隅角进行抽放，另一趟埋入采空区进行埋管抽放，通过进行两趟管路抽放，可有效地遏制采空区瓦斯涌出，消除工作面上隅角瓦斯积聚现象，确保工作面安全生产。

This paper takes the fully mechanized face of Yuecheng mine 1302 for example ,Yuecheng mine be-longs to Jincheng Mining Group in Shanxi.It talks about the gas emission law and governance principles which happens in the gob with U Type ventilation .The research proves that , with laying two goaf pipelines in the ven-tilation roadway , one inserts into the upper corner to drainage and the other one embeds into the gob to drain -age, it can effectively prevent the gas in the gob from emitting , and can eliminate the gas accumulation at the upper corner in the working face and ensure the safety of production in the working face .
