| 摘 要： | 根据分形理论，提出了煤体表面裂隙迹线长度－条数分维Ｄ和网格尺度－裂隙视条数分维ｄ的测量方法及两种分维的线性相关性和互通性。通过对１１个不同变质煤层微观与宏观裂分维ｄ的测量，证明了煤体内裂隙尺度的分布具有自相似性，并且分维值随煤变质程度不同呈有规律性地变化。用实例说明了裂隙分布分形研究在定量表示煤岩体工程特性方面具有要意义。

| Abstract: | Based on theory of fractal geometry, two measuring methods, namely, the fractal dimension D(trace length-number of cracks )and d(grid scale-visual crack number in coal) as well as the linear correlation and interchangeability between D and d are described. The self-similarity of the crack distribution and the variation of the fractal dimension values with metamorphism are of regular confirmed by the measurement d of macro and micro cracks in samples from eleven coalmines. It is shown by practical examples that fractal study of crack distribution is of important significance in quantifying the engineering properties of coal and rockmass. |
