| 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. |
