Evaluation of Particle Size Distribution of Coal Gangue through Fractal Method in Dongkuang Mine, Heshan, China
Publication: Journal of Materials in Civil Engineering
Volume 26, Issue 8
Abstract
The particle size distribution of coal gangue was obtained from a sieving experiment and the representative grading calculated using the statistical values of coarse grain content. A fractal method was proposed and fractal dimension deduced based on the accumulated mass distribution function. The results indicate that when the value of is between 1.89 and 2.63, coal gangues are well graded. The use of a fractal method can help to avoid errors associated with calculating grading parameters ( and ) in traditional theory, and the fractal dimension can also be used to evaluate the compactability of coal gangues and other bulk materials.
