摘　　要：介绍了晋城煤业集团煤层气储量及赋存特点,阐述了"先抽后采"、采煤采气一体和"三级"瓦斯治理的模式、方法及配套抽采方式和工艺。重点叙述了"井上下抽采相结合,井上抽采先行;抽采利用相结合,以用促采",开创了高瓦斯矿井煤层气抽采利用新局面。Reserves of coal seam gas and storing of coal seam gas in Jincheng Coal Industry Group are introduced. The techniques of cramping out first and producing next, compact gas production and mining are expounded. The three - grade gas control methods and cramping out and producing techniques are also introduced. In this paper, the author mainly tells the techniques of combining inside and outside mining gas production with gas production outside mining first, combing gas production and gas application. The author points out that these techniques improve gas withdrawal and production in highly gassy mine.
