2328综采工作面瓦斯涌出综合治理

Complex Control of Gas Emission in 2328 Fully Mechanized Coal Face

采用穿层钻孔、顺层钻孔、采空区埋管相结合的方法,提高了工作面瓦斯抽放率。在最大限度地保证工作面配风量的同时,采用抽排风机对上隅角瓦斯进行抽排,效果良好,且抽排风筒内瓦斯浓度始终符合有关规定,解决了2328综采工作面瓦斯涌出问题,确保了矿井安全生产。

The gas drainage rate in the working face was improved by the method combining crossing holes with holes along seam and burying pipes in the gob.While maximally ensuring the air distribution in the face,exhausting fan was used to discharge the gas at the upper corner angle of the face,better effect was achieved.The gas concentration in the exhausting duct always met relevant requirement,this thus solved the gas emission in 2328 fully mechanized face and ensured the safe production of the mine.
