摘　　要：根据煤层气抽采的相关概念及解吸吸附原理,分析了国内外煤层气采收率的现状,依据铁法盆地的煤层气地质条件,通过对现有资料及实际测定数据的分析计算,得出铁法盆地煤层气采收率约为39.88%-64.73%的结论,认为具有较高的开采价值。According to the conception related to CBM recovery and the principle of isothermal adsorption, through analyzing the CBM geological condition, the CBM recovery rate in Tiefa coal basin ranges from 39.88% to 64.73%. The calculation of CBM recovery rate is based on the existing data and some of on-site measured production parameters, and it accords with the practical situations both in USA and Tiefa.
