摘　　要：煤层气是煤的伴生矿产资源,热值是煤的2~5倍,属于非常规天然气。习惯性称为瓦斯。主要以吸附态赋存于煤孔隙中(70%~95%),少量以游离状态自由地存在于割理和其他裂缝或孔隙中(10%~20%),极少量以溶解态存在于煤层内地下水中。开发利用煤层气资源能大幅增加气化云南气源多源性,减少煤矿瓦斯对空排放量,有效缓解温室效应,同时能遏制矿井瓦斯事故,达到安全生产。滇东地区煤炭及煤层气富集区以恩洪、老厂矿区为最好。合理、科学规划煤矿区优先采气后采煤,使地面(井上)与井下瓦斯抽采协调发展,生产达到零瓦斯、零事故,为煤炭高质量发展及高瓦斯矿井综合治理做出贡献。Coalbed gas is the associated mineral reources of coal,thermal value is coal times 2-5,belonging to the unusual natural gas,called gas in habit.It is mainly in the small opening hole of coal(70~95%).A little of it is in cleatand other crack or small opening hole in free state(10~20%).,a tiny minority of it is in the under ground water of coalbed in dissolved state.The development-utilization of coalbed gas resouces can realty increase the variety of gas resources n Yunnan,decrease the exhaust of coal field gas,effectively get rid of the greenhouse effect,and check the gas accident of shaft,achieve the safety in production.In E Yunnan,the best coal and coal bed gas concentration areas are Enhong and Laochang orefield.Reasonable scientific planning the coal orefield,exploitation gas in advance,coal mining later,let the surface and shaft extraction exploitation coordinate growth,production can realize zero gas,zero accidence,in order to achieve contribution for coal high quality development and high gas mine comprehensive administration.
