| 摘 要： | 通过对淮南、淮北两个研究区内各煤矿不同煤级煤样进行的压汞法孔隙测量结果的分析，表明用分形维数可以表示煤的孔隙结构特征，而且煤孔隙体积分形维数随着变变质程度的增高而减小，渗透性随煤级的增加而减弱。

| Abstract: | Through analyses on measure results of coal pore with mercury porosimetr y for different ranks of coal from each coal mine in both research areas of Huainan and Hu aibei,indicated that pore textural features of coal may be expressed wit h fractal dimensions,and that fractal dimensions of coal pore volume decreased along with increasing of ranks of coal,and the permeabi lity is also decreased along with increasing of ranks of coal. |

| Keywords: | fractal dimension texture of pores mercury porosimetry ranks of coal |
