选择平顶山十二矿和焦作中马村矿不同煤体结构的肥煤和无烟煤进行低温液氮吸附实验，分析研究变形煤的孔隙特征及其分形特征。研究表明，过渡孔和微孔是煤层气吸附发生的主要场所，其中微孔起着重要作用；分形维数反映了煤的煤化程度，即分形维数越大、煤化程度越深；分形维数表征孔容按孔径大小变化的分布特征，且分形维数与孔容含量有较好的相关关系。

Fat-coal of the twelfth mine in Pingdingshan and blind-coal of Zhongma mine in Jiaozuo for different coal body structures were selected and tested by the low-temperature nitrogen adsorption method to analyze the coal pore properties and fractal features. The results show that the transition pore and micro-pore are the primary site of coal bed methane adsorption,and micro-pore plays an impor-tant role. The fat-coal fractal dimension is greater than the blind coal fractal dimension. The fractal dimension of fat-coal and blind coal gets larger with the damage of coal deepening. The fractal dimension has a good relative with volume content,which expresses pore vol-ume distribution properties well.
