摘　　要：瓦斯是煤炭伴生的清洁能源,同时也是煤矿重大灾害的隐患。瓦斯单独开采的价值远远低于煤炭本身。但是作为煤炭伴生能源进行开采既可提高矿井开采效益,又可一定程度上消除其灾害隐患。根据我国煤层透气性低、埋深大等特点,利用采动卸压场与裂隙场实现煤与瓦斯共同开采是我国瓦斯能源开采的正确模式,进一步研究采动裂隙场的解吸性、透气性、瓦斯与裂隙场的耦合作用关系、提高瓦斯抽放浓度与完善低浓度瓦斯的利用技术等是实现瓦斯开采和利用的关键问题。Methane is the associated clean energy of the coal and is a potential disaster of the mine.The value of the gas extraction individually is far lower than the coal value.As an associated energy,the extraction of gas could improve the mine mining benefit and could eliminate the disaster in potential in mine.Base on the low gas permeability,deep mining depth and other features of the coal seam in China,with the application of the mining strata pressure releasing field and the strata cracking field,the co-minin...
