摘要：
为探求华北区域煤样的孔隙发育特征，采用压汞法对采自此区域不同煤阶样品孔隙结构和分形维数进行研究。研究结果表明煤体孔容和比表面积分别由大孔和微孔发育情况所决x定，且100nm
关键词: 煤阶, 孔隙结构, 华北区域, 压汞
Abstract:
The pore structure characteristics and fractal dimension of coal acquired from North China are investigated by using mercury intrusion method. The results show that the pore volume and specific surface area of coal are determined by development of big porous and micro porous respectively, and as the change of Ro,max the pore volume and specific surface area of coal change curves appear higher both end and lower middle; when pore diameter exceed range from 50.4 to 95.4, the pore diameter appear fractal characteristics and as the increase of Ro,max the fractal dimension present decreasing trend as a whole.
Key words: coal rank, pore structure, North China, mercury intrusion
