摘　　要：某矿为了优化工作面布置方式,提高回采率,缓解采掘接续紧张等问题,工作面布置方式由U+L型变为简单的单U型。根据煤层赋存情况及瓦斯涌出量特征,在合理的通风系统及充足的配风基础上,采取了综合瓦斯治理措施,掘进采取边掘边抽+释放钻孔,回采采取单侧顺层定向本煤层钻孔+顶板倾向定向钻孔+上隅角埋管瓦斯抽采等技术措施。通过以上瓦斯治理技术,有效解决了高瓦斯煤层单U型通风工作面采掘过程中的瓦斯问题,经济和社会效益显著。In order to optimize the layout of working face,improve the recovery rate and alleviate the tension of mining and excavation,the layout of working face changed from U+L type to simple single U type.According to the occurrence of coal seam and the characteristics of gas emission,on the basis of reasonable ventilation system and sufficient air distribution,comprehensive gas control measures are also adopted.The excavation adopts the technical measures of excavation and drainage+release drilling,and the mining adopts the technical measures of unilateral bedding directional coal seam drilling+roof tendency directional drilling+upper corner buried pipe gas extraction.Through above gas control technology,the gas problem in the mining process of single U ventilation working face in high gas coal seam is effectively solved,and the economic and social benefits are remarkable.
