Research on Optimization of Electric Control System for Mine Belt Conveyor

In order to promote the energy-saving and consumption reducing operation of the belt conveyor, based on the operating principle of the belt conveyor electric control system, the belt conveyor electric control system was optimized. The hardware and software parts of the belt conveyor electric control system were designed, and application testing was carried out. The results showed that by applying intrinsic safety sensors and PLC programmable controllers, the operating conditions of the belt conveyor could be monitored in real time, better ensuring the safe and stable operation of the belt conveyor. After optimization, the belt conveyor electric control system can reduce 2 operating positions, save 1.2×10⁵ yuan in annual wage expenses, reduce the weekly electricity consumption of the belt conveyor by 30857 kW·h, reduce the operating cost of the belt conveyor, and promote energy-saving and consumption reducing of the belt conveyor operation.
