| 摘 要： | 运用分形理论分析了伯方煤矿3号煤层煤样冲击产尘的粒径分布特性，得出：冲击煤尘粒径-质量之间存在明显的分形特性.随着冲击高度和冲击次数的增加，产生微细粉尘的总量也在增多，反映在ln d-ln W曲线上即为直线的斜率变小，分形维数D在不断增大.从而为定量地描述煤尘粒径分布特性规律提供了一种新的方法.

| Abstract: | Using the fractal theory to analyse the impacting dust particle-size distribution characteristics of Bofang Mine No.3 coal seam's coal sample,then it comes to the conclusion that it exists obviously fractal characteristics between the particle-size of impacting coal dust and its weight.And with the increase of impact height and impact times,the total of the tiny dust is increased too.Reflected on the ln d-ln W curves means the slope decreasing and the fractal dimension D increasing.It offered a new method to describe coal dust particle-size distribution characteristics quantificationally. |
