Abstract：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 .
