AI Technical Summary
Existing technologies for coal and gangue identification suffer from low accuracy, missed detections, and false alarms. They are particularly difficult to effectively distinguish between coal blocks and gangue in complex underground environments. Furthermore, existing methods pose health hazards and environmental pollution risks.
A coal and gangue identification method based on laser reflection is adopted. The coal and gangue are moistened by a spray device on a scraper conveyor, and a laser irradiation device emits a laser of a specific wavelength. The reflected laser energy information is received by a laser receiving device, and the coal and gangue are distinguished according to the intensity of the reflected laser energy.
It improves the accuracy and efficiency of coal and gangue identification, avoids manual intervention and environmental pollution, and achieves safe and efficient coal and gangue sorting.
