据统计资料中国煤层气资源量为30×10～35×10m,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10×10m.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0.43×10～0.65×10m,2000～2010年将是我国煤层气的大发展阶段,预计全国可达20×10m,2020年产量将达100×10m,2050年达到250×10m.

According to statistic data, China's coal-bed gas resources are 30×10～35×10m.Excepting the loss resulted from buried depth, metamorphism, gas weathering zones and coalfield structures, the actural recoverable coal-bed gas resources are only 10 ×10m.Based on the process of American coal-bed gas exploration, it is predicted that China's coal-bed gas production would be 0.43 ×10～0.65 × 10m in 2000 , it will be 20 ×10m in 2000～2010 , 100×10m in 2020 and in the year of 2050 ., the production will be 2050 ×10m.
