Abstract: For problems of high energy consumption of belt conveyor and inability to adjust control automatically according to actual coal quantity, a coal mine belt conveyor control system based on load detection was designed. Overall load and material distribution of belt conveyor are obtained in real time through load detection device. Running speed of belt conveyor is automatically controlled according to the overall load, and start-up along coal flow of multi-level series belt conveyor is realized according to material distribution. The application result shows that the system realizes less human operation management of belt conveyor, reduces energy consumption and improves transportation efficiency.
