摘要
采用直接解吸法、等温吸附法和吸附—解吸法，对研究区上古生界主煤层中煤层气的采收潜势进行分析，得出了一些有意义的结论：在０．７ＭＰａ废弃压力水平，推定区中绝大部分矿区的主煤层将可能没有煤层气产出；推断—预测区主煤层的采收潜势以临汾盆地最好，沁源东—安泽和沁水—翼城地区上主煤层也相对较高，而下主煤层普遍较差或极差。
Based on the methods such as direct desorption,isothermal adsorption and combined adsorption desorption,the recoverable potential of the CBM in the Upper Paleozoic main seams of the southern Shanxi was studied,and some significant conclusions were suggested.At the level of 0.7MPa abandoned pressure,the CBM might be hardly produced from the main seams in the most mining districts of the indicated areas.As for the referred predicted areas,the CBM recoverable potential minght be high in the main seams of the Linfeng basin,relatively high in the upper main seam of the eastern Qinyuan Anze and Qinshui Yicheng areas,and low or very low commonly in the lower main seam
