摘　　要：介绍了陈家山井田煤层气的成分及分布规律，利用扫描电镜、压汞实验、吸附实验等手段，分别对煤层的孔隙特征及吸附性能进行了分析和研究－ 根据井下抽放实验，得知４ － ２ ＃ 煤层为勉强可抽放层，煤层顶板砂岩为可抽放层的结论－ 图５ ，表２ ，参６－The author concisely introduced the coal-gas composition and its distribution.Then with electroscan microscope and by press-mercry experiment and absorption experiment,the pore character and absorbtive behavior of coal were studied and analysed respectively.In the end,according to the underground drawn experiment and using a series of indexes,a conclusion is obtained that the 4-2 # coalbed is a reluctantly drawnable layer,and the roof-sandstone is a drawnable bed.5figs.,2tabs.,6refs.
