摘　　要：玉华煤矿针对1401综采工作面在初放期间出现瓦斯涌出量大,易出现回风隅角瓦斯超限的问题,采取高位钻场瓦斯抽采、临巷瓦斯抽采和采空区瓦斯抽采等综合治理技术,有效解决了1401综采工作面瓦斯涌出量大的问题,避免了瓦斯超限问题,为工作面安全生产创造了条件。The 1401 fully-mechanized working face of Yuhua Coal Mine has a large amount of gas emission during the initial caving period,which leads to risk of gas outbursts in the return air corner.To solve this problem,the authors adopted several technologies,including high-level borehole gas extraction,sideway gas extraction,and gas extraction in gob.The result showed that the problem of gas emission and gas overrun was effectively solved at the 1401 fully-mechanized working face,which created good conditions for the safe production of working face.
