摘　　要：针对我国每年有180亿m3以上的纯甲烷混入矿井风流中通过乏风排空的现状,为有效回收这些资源,深入研究相关的煤矿乏风瓦斯富集分离技术十分必要。通过介绍吸收法、深冷分离法、膜分离法、变温吸附(TSA)和变压吸附(PSA)等用于煤矿乏风瓦斯富集分离的技术方法等,综合分析了各项技术的优缺点,并提出变压吸附技术被认为是最具有发展前景的煤矿甲烷富集技术。同时,将煤矿乏风瓦斯富集分离的研究方法应用于环保教育,也取得了良好的教学效果。More than 1. 8×1010m3methane mixed with ventilation air from coal mine were vented. In order to recover these resources andreduce waste gas emission effectively,in-depth study related to ventilation air methane enrichment and separation technology in coal minewas necessary. A series of enrichment and separation technologies of ventilation air methane in coal mine were introduced,including ab-sorption method,cryogenic separation and membrane separation, temperature swing adsorption（ TSA） and pressure swing adsorption（PSA）. Through comprehensive analysis and comparing the advantages and disadvantages of various technologies,the results showed thatPSA technology should be one of the most development prospects for coal mine methane concentration and utilization. At the same time,theresearch methods of enrichment and separation technology were also used to support environmental protection education,and the studentswere interested in experiment and had gotten many achievements.
