Abstract：As the key equipment in coal mine production, belt conveyor is very important to ensure the reliable and stable operation of the equipment. In this paper, the automatic control system of DTL140 belt conveyor in Jingfang Coal Industry is studied. The selected PLC controller model is S7-300, using speed sensor and speed sensor model is SS102K and GSD-5, respectively, to detect the belt speed and motor speed. According to the test results, the system can adjust the motor speed to ensure the power balance between the two motors. The automatic control system has achieved good results in coal mine engineering practice, and the operation stability and reliability of belt conveyor are significantly improved.
