In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm.2.1 Coal sample preparation and image acquisition. Twelve coal samples from different sites in the Sihe mining area were selected and numbered. These samples were processed and imaged as follows: (1) Samples with more flat surfaces were cut into thin slices; (2) The surfaces of these slices were cleaned with acetone to remove any Two-dimensional SEM image-based analysis of coal porosity

Image segmentation method for coal particle size
Coal samples with particle sizes ranging from 0.25 to 2.5 mm were obtained from the teetered bed separator feed of the Liuwan coal preparation plant, Shanxi province. To reduce the influence of moisture on image segmentation, the coal samples are dried before the images are captured.The experiment results showed that the images of coal and gangue can be precisely recognized based on RS-EEM under the influence of long running pollution and similar background grayscale, and the recognition accuracy can reach to 96.15% as well as grasping accuracy to 85% at 0.4 m/s conveyor belt speed. ABSTRACT The recognition Recognition and sorting of coal and gangue based on image
