| description | The invention relates to a top coal caving mining process gangue mixed ratio control system based on a grayscale recognition technology. The top coal caving mining process gangue mixed ratio control system comprises a photographing device, a system main machine, a top coal caving controller, a hydraulic support electric-hydraulic control system and a hydraulic support, wherein the photographing device is used for monitoring the process of discharging coal and gangue from a tail beam coal caving opening of a hydraulic support in real time and continuously photographing coal and gangue discharging images; the system main machine is used for collecting, preprocessing and analyzing the coal and gangue images and acquiring two evaluation indexes, namely, the particle size of the coal and the gangue and the respective occupying ratio of the coal and the gangue, the top coal caving controller is used for comparing the evaluation indexes with a preset threshold value and transmitting an instruction for closing and opening the coal caving opening to the hydraulic support electric-hydraulic control system. By adopting the top coal caving mining process gangue mixed ratio control system, the problems that the gangue mixed ratio control effect is poor, the resource is severely wasted, and the body health of the operation personnel is severely harmed by adopting the manual coal caving way in the top coal caving mining process can be effectively solved. |
