摘要
煤层甲烷是指富存于煤层中的天然气，90％以上都是由CH4组的，煤层中甲烷具有埋深浅、勘探成功率高的优点。我国煤层甲烷资源十分丰富，开发煤层甲烷对于改变我国能源构成、降低矿井瓦斯、减少温室气体排放都具有重要意义。本文介绍了煤层甲烷的形成与散发。
Methane in coal seams is referred to natural gas accummulated in coalbeds. Over 90 percent of it consists of CH4, and it has many advantages such as shallow burial and exploration easily. Methane resource of coal seams in China is veryabundent. Developing methane in coal seams is important for changing energy-sourcestructure and decreasing mine gas and green-house gas of China.The paper presents formation and disspation of methane and development and utilization of methane resource in coal seams.
