结合煤粉制备过程的物理实质建立了山西灵石煤原生煤粉和磨制煤粉的灰分、硫分分形模型,分析可知分形维数在表征煤粉灰分、硫分分布特征上有很好的效果,分形函数的统计相关性达0.91以上,有利于了解原生煤粉和磨制煤粉之间的差异.在细粒级别时,煤样的灰分、硫分含量比较大.

This paper established fractal model of Lingshi indigenous and grinding coal ash and sulfur in Shanxi combined with coal preparation process of the physical nature.We can draw that the fractal dimension can be very good reflect the characteristics of distribution of coal and sulfur,and fractal function statistical correlation is over 0.91,which helps us understanding of the difference between indigenous and grinding coal.And then,it contains more ash and sulfur when coal sample fraction diminishes.
