摘　　要：针对18205采煤工作面受瓦斯频繁超限影响的问题,通过应用高位裂隙孔及上隅角悬管综合瓦斯抽放技术,有效地降低了瓦斯浓度,保证了工作面的安全回采,取得了较好的技术经济效果。In view of the problem that the 18205 coal mining face is affected by the frequent gas overrun, through the application of integrated gas drainage technology in high fissure aperture and suspended pipe in upper corner, the gas concentration is limited and the safe mining of the working face is ensured with good technical and economic results.

关 键 词：采煤工作面 瓦斯超限 综合抽放技术 安全回采
