| 摘 要： | 借助现代分形理论的基本思想和原理,提出了测量裂隙数量的方法。在此基础上,利用回归分析的方法对所选矿区测量结果进行量化分析研究,建立了煤体单轴抗压强度与裂隙条数之间的指数衰减关系式。实现了分形理论与统计理论相结合对数据的分析和处理,为工程实践中评价煤层强度与裂隙发育状况的关系提供了一种可操作性途径,具有一定的实际意义和指导意义。

| Abstract: | By means of the basic idea and principle of the modern fractal theory,the method to measure the cracks quantity in or on the face of a coal block is put forward.Based on this foundation,make use of analysis of regression to analyze the measure result in the typical coal sample of the selected coal mine,so the relation between uniaxial compression strength and the number of crack is set up as a reduced exponential formula.This text combined the fractal theory and the statistic theory in the processing and analyzing of data,provided a kind of manageable evaluated path for the relation of the strength of coal seam and the condition of the cracks development in engineering practices. |

| Keywords: | cracks strength of coal seam uniaxial compression strength fractal theory |
