抽放煤层气是减少矿井瓦斯涌出量、防止瓦斯爆炸和突出事故的根本措施．煤层气是一种洁净能源，热效率高，尤其在当今我国能源结构不合理的情况下，加快煤层气的勘探、开发和利用具有巨大的社会效益和经济效益．从含煤盆地、成煤时代、煤层气的储层类型和埋藏深度等方面论述了我国的煤层气资源，并讨论了我国煤层气的开发现状． Draining CBM is the fundamental measure to reduce gas emission from mines, prevent gas explosion and highlight accidents. Coal bed methane is a kind of clean energy with high thermal efficiency. Especially in the current unreasonable energy structure in our country, it has great social and economic benefits to speed up CBM exploration, development and utilization. The CBM resources in China are discussed from coal-bearing basins, coal-forming age, coalbed methane reservoir types and burial depth, and the development status of CBM in China is discussed.
