万峰煤矿综采工作面上隅角瓦斯综合治理技术

Comprehensive control technology of corner gas in fully mechanized mining face of Wanfeng Mine

为了解决万峰煤矿1209综采工作面上隅角瓦斯超限问题,本文针对综采工作面上隅角瓦斯来源,同时结合现场条件,探索应用分源抽采、合理配风、构筑隔离墙等综合治理方法,通过实践证明该方法能有效解决上隅角瓦斯超限问题,使采面上隅角瓦斯浓度降至0.5%以下,保证了综采工作面的正常回采,为实现矿井安全高效生产创造了条件。

In order to solve gas overrun in upper corner of 1209 fully mechanized working face angle roadway of Wanfeng Mine,the upper corner gas source,combining with the field condition,the application of point source extraction,the reasonable air distribution,comprehensive treatment methods,such as building wall through technology were explored,the practice proved that this method can effectively solve the problem of gas overrun in upper corner,make mining top corner gas concentration below 0.5%,guaranteed the normal recovery mining of fully mechanized working face,created the conditions to realize efficient mine safety production.
