摘要
通过研究表明，孔隙煤体是一种分形体，其中的孔隙裂隙分布符合分形分布规律，运用分形理论可对煤体的孔隙率、比表面积等物理特性进行定量化的描述。
Through study this paper shows that porous coal is a kind of fractal material, in which the distribution of hole and crack conforms to the fractal distribution law. Using fractal thoery we can describe porosity, specific surface area and other coal characteristics in quantity, which is very important to study physical and mechanical characteristics of coal in thoery and practice.
