综述了煤矿瓦斯增抽方法、离子液体溶胀煤、离子液体溶解甲烷的研究现状；分析了目前低透煤层瓦斯增抽主要是采用物理作用破碎煤体来释放CH4，或注CO2或N2置换瓦斯的办法，其效果虽然显著，但对于微孔隙中的甲烷解吸还是存在着局限性．鉴于功能化离子液体溶胀煤及吸收甲烷的协同作用，提出利用离子液体增加煤中孔隙尺寸以吸收煤表面CH4气体的方法，强化抽采过程中的瓦斯解吸，降低了煤层本身的瓦斯含量，提高抽采瓦斯气体的利用效率．最后，阐述离子液体溶胀煤、溶解甲烷的研究进展，以及离子液体应用于瓦斯抽采方面的研究基础．

The current researches about eoalmine gas extracting improvements, ionic liquid （IL） swelling coal and ionic liquid dissolving gas were summarized. The current methods of gas extracting .from low - permeability coal seams mainly include physically cracking to release methane or injecting CO2 or N2 to replace the methane, which are practically efficient. However, they are limited for desorption of methane in the coal micropores. Considering that certain ionic liquids can efficiently swell and disperse coal, and dissolve methane, we suggest a new idea to use ILs to increase pore size of coal, and simultaneously absorb methane, helpful for impelling methane to desorb from coal and increase the concentration of the extracted gas. From two aspects, swelling coal and dissolving CH4, it is confirmed that there is the research foundation in using ionic liquid to enhance the CH4 release from coal.
