摘　　要：本文主要分析了低瓦斯矿井综采放顶煤工作面上存在的问题,重点介绍了上隅角氧气管理主要是矿井通防管理中的工作重点,并且也是通过加大工作面风量的方式来达到上隅角瓦斯浓度降低的主要目的,它不仅可以进一步分析出工作面瓦斯源的构成要素,还能通过分源治理的理念来利用顺层平行孔与扇形钻孔相结合的方式抽取瓦斯。通过对该问题的研究和分析,进一步可以确保煤矿生产过程中的安全性和稳定性,也能提高煤矿开采的经济效益。This paper mainly analyzes the problems existing in fully mechanized top-coal caving face in low-gas mine,and emphatically introduces that oxygen management in upper corner is the focus of work in mine general prevention management,and it is also the main purpose of reducing gas concentration in upper corner by increasing air volume in working face.It can not only further analyze the components of gas source in the working face,but also extract gas by combining parallel holes along the bed with fan-shaped drilling holes through the concept of separate source control.Through the research and analysis of this problem,we can further ensure the safety and stability in the coal mine production process,and also improve the economic benefits of coal mining.
