煤層氣是煤的伴生礦產(chǎn)資源,與天然氣是同一種性質(zhì)的可燃性氣體,其組成主要為甲烷,還含有少量的氧氣、氫、二氧化碳以及烴類化合物,是一種熱值高且無污染的新型能源。一般把煤炭開采過程抽排出甲烷濃度大于25%的瓦斯稱為高濃度煤層氣。煤層氣中的甲烷濃度是確定煤氣資源儲量、豐度及開采的重要參數(shù),可綜合煤層的面積、厚度等條件預(yù)測煤礦的產(chǎn)氣能力,并制定勘探開發(fā)方案。

　　Coalbed methane is an associated mineral resource of coal, which is a combustible gas with the same properties as natural gas. Its composition is mainly methane, and it also contains small amounts of oxygen, hydrogen, carbon dioxide, and hydrocarbon compounds. It is a new type of energy with high calorific value and no pollution. Generally, gas with a methane concentration greater than 25% discharged during coal mining is called high concentration coalbed methane. The methane concentration in coalbed methane is an important parameter for determining the reserves, abundance, and extraction of coal gas resources. It can predict the gas production capacity of coal mines based on conditions such as the area and thickness of coal seams, and formulate exploration and development plans.
