Current status and development trend of measuring methods of conveying capacity of mine-used belt conveyor

Measuring methods of current mine-used belt conveyor were analyzed, which are electronic belt scale measuring method, nuclear belt scale measuring method, ultrasonic ranging measuring method, laser CCD image measuring method and laser scanning measuring method. Various methods were compared and analyzed from aspects of measurement accuracy, response time,etc. In contact measuring methods, electronic belt scale measuring method has high measurement accuracy, but response speed is slow and stability is poor. In non-contact measuring methods, laser scanning measuring method has high measurement precision, high response speed and good stability. It is indicated that development trend of measuring methods of conveying capacity is to improve measurement accuracy, anti-interference and adaptability; non-contact measurement method or a method combining various technologies will gradually become the mainstream measuring methods of conveying capacity.
