煤的分形孔隙结构特征的研究

通过用分形理论进一步研究了煤的孔隙结构，通过煤的孔隙结构分形特征把扎隙结构划分为3种孔隙系统，即大孔、中扎和微孔，探讨了分维D2的物理意义及同煤质的关系，初步提出分维D2可以用来作为煤与瓦斯突出的预测指标。

Research into the Fractal Character of Pore Structures in Coal Fushun Branch of CCRI

Based on the fracta1 theory, this paper has made a further research on the pore structure in coal,and according to the fractal character of pore structure in coal, the pore structures are classified into the following thee types i. e. the macropore, the mediumpore and the micropore. Investigation has also been made into the relationship between the value of coal's fractai dimension (D2) and the nature of coal with the conclusion having been drawn that D2 could be taken as the index for prediction of coal and methane outbursts.
