老窑沟煤矿综采工作面瓦斯综合防治技术应用

Application of comprehensive gas control technology in fully-mechanized mining face of Laoyaogou Coal Mine

以老窑沟煤矿1151综采工作面为研究对象,针对工作面煤层瓦斯涌出量大的问题,采取了本煤层瓦斯抽放、高位钻孔瓦斯抽放、采空区埋管瓦斯抽放等瓦斯综合防治技术。经过为期4个月的治理,1151综采工作面生产期间实现了瓦斯“零超限”的目标,取得了预期的瓦斯治理效果。

Taking the 1151 fully-mechanized mining working face of Laoyaogou Coal Mine as the research object,in view of the problem of large coal seam gas emission in the working face,the gas drainage of the coal seam,the gas drainage of the high-level drilling,and the gas drainage of the buried pipe in the goaf were adopted.After 4 months of comprehensive gas prevention and control technology,the 1151 fully-mechanized mining face achieved the goal of"zero excess gas limit"and achieved the expected gas control effect.
