Fractal feature of coal mine waste discrete material
【摘要】 应用分形几何理论对徐州地区的煤矸石散粒料进行了粒度分析 ,并研究了几个矿区煤矸石散粒料的粒度分布的分维 ,研究表明煤矸石散粒料具有分形结构特征 ,散粒材料的粒度级配特征参数———不均匀系数Cu=61 /( 3-D) 、曲率系数Cc=1 .5 1 /( 3-D) ,同时研究了煤矸石的击实特性和强度特性与分维特征的关系
【Abstract】 The grading analysis of the coal waste discrete material from Xuzhou region are performed by using the fractal theory. The fractal dimension of the grain size distribution of the coal mine waste discrete material from several coal mines is also studied. The research results show that the coal mine waste discrete material possesses fractal structure feature. The characteristic parameters of the grain size gradation can be described by the fractal dimension - C u=6 1/(3- D ) and C c=1.5 1/(3- D ) . Meanwhile, the relationship between compaction feature and fractal dimension and the relationship between shear strength and fractal dimension of the coal mine waste discrete material are investigated.
