低浓度瓦斯利用促进了沿沟煤矿瓦斯抽采

Gas Drainage in Yangou Colliery and Application of Low-concentration Gas

为了确保低浓度瓦斯发电项目取得成功,沿沟采取了寻找瓦斯源、优化抽采方案、增加抽采工程量等技术措施,攻克了瓦斯抽采浓度过低、抽采瓦斯量不足的难关,保障了低浓度瓦斯发电项目的正常运行。

To assure the accomplishment of low-concentration gas power project,the authors take technical measures,such as looking for gas origin,optimizing drainage plans and increasing drainage quantity,to guarantee the normal operation of low-concentration gas power project by solving the problems of low gas drainage concentration and inadequate gas drainage quantity.
