摘　　要：结合张集煤矿11418首采工作面煤层赋存条件等相关参数,分析了工作面瓦斯来源,测定并分析了煤层瓦斯含量、工作面推进速度、瓦斯抽采量、煤层厚度、煤层埋深与瓦斯涌出量之间的关系,结果表明:综采工作面瓦斯涌出量包括煤壁瓦斯涌出量、采空区瓦斯涌出量及落煤瓦斯涌出量。11418首采工作面瓦斯涌出量与瓦斯含量、推进速度、煤层厚度、煤层埋深呈正比关系;瓦斯涌出量随抽采量的增加呈波浪式变化,总体上递增,但增加的幅度不大。This paper analyzed the gas source in 11418 first-mining working face in ZhangJi Mine,determined the coal seam gas content,the face advance speed,the gas drainage and extraction amount,the coal thickness and the coal buried depth and analyzed the relation between them and the gas emission according to relevant parameters such as the coal seam occurrence conditions in this face.The results showed that the gas emission in the fully mechanized face should include the gas emission from the coal wall,the gas emission from the gob and the gas emission in coal breaking.The gas emission in 11418 first-mining face was directly proportional to the coal seam gas content,the face advance speed,the coal thickness and the coal buried depth,the gas emission assumed wave change with the increase of gas drainage and extraction amount,it increased in general,but the increasing range was not big.
