摘　　要：煤矿乏风中甲烷富集增浓技术是制约低浓度煤层气利用的关键技术。在分析国内外学者从不同工艺、材料、方法对煤矿乏风中甲烷富集增浓研究的基础上,总结了低温精馏法、膜分离法、溶液吸收分离法、吸附分离法、水合物合成法的优缺点和研究进展。通过分析对今后煤矿乏风中甲烷的利用前景进行了客观展望。The technology of marsh gas concentrating for VAM was the key technology,which restricted the utilization of low concentration coal- bed gas. Based on the analysis of research on the technology of marsh gas concentrating for VAM of domestic and foreign scholars from different technology,material and method,the staged results and breakthrough were summarized. The separation effect, advantages and disadvantages of cryogenic distillation,membrane separation process,solution absorption process,adsorption stripping process and hydrate synthesis process in different condition were analyzed simultaneously. The utilization prospect of low concentration coal- bed gas was viewed objectively.
