Design of intelligent control system for continuous gangue discharging of whole rock roadway based on PLC

In order to improve gangue discharging efficiency, an intelligent control system for continuous gangue discharging of whole rock roadway based on PLC was designed according to gangue discharging technics consisting of excavator, belt conveyor, continuous gangue seperator and tramcar. Functional requirements of the system were introduced, and overall control scheme and control flow of the system were analyzed in details. The industrial application results show that the system has safe and stable operation, and gangue discharging efficiency increases 20%.
