Introduction of Coal Gangue. Gangue, also called coal gangue, is the solid waste discharged in coal mining process and coal washing process, black rock harder than coal. Its carbon content is low and exists along with coal seam. Gangue could be found in roof, bottom board, inter-layer, and it could be selected in washing process.
4.1 Design and implementation of coal gangue detection and recognition device. This study proposes an method for coal gangue detection and recognition on the basis of the DCN-YOLOv3 algorithm. Firstly, the method collects real-time video images of a conveyor belt operation through an industrial camera erected perpendicular to the conveyor belt.
Coal gangue is a harmful solid waste product of coal mining. When it accumulates for a long time, it becomes harmful to the surroundings.
