据统计资料中国煤层气资源量为３０×１０１２～３５×１０１２ｍ３，若排除埋藏深度、变质程度、瓦斯风化带及煤田构造的影响，实际可供勘探开发的煤层气资源量只有１０×１０１２ｍ３。根据美国煤层气勘探的历程，预测我国煤层气产量在２０００年将达０．４３×１０８～０．６５×１０８ｍ３，２０００～２０１０年将是我国煤层气的大发展阶段，预计全国可达２０×１０８ｍ３，２０２０年产量将达１００×１０８ｍ３，２０５０年达到２５０×１０８ｍ３。
According to statistics, the amount of CBM resources in China is 30 × 1012 ~ 35 × 1012m3. Excluding the burial depth, metamorphism, gas weathering zone and coalfield structure, the actual available CBM resources for exploration and development are only 10 × 1012m3. According to the history of coalbed methane exploration in the United States, it is predicted that the output of CBM in China will reach 0.43 × 108 ~ 0.65 × 108m3 in 2000, and the development phase of coalbed methane in China from 2000 to 2010 is expected to reach 20 × 108m3,2020 annual output will reach 100 × 108m3, in 2050 to 250 × 108m3.
