The traditional relay control is being eliminated and renewed in the rapid development of industrial control field because of its huge volume, high failure rate and slow response speed. PLC control mode has the advantages of quick response, multiple use of internal contacts, simple structure, small occupation of land and low accident rate. This design adopts PLC control, which can greatly improve the safety performance of the belt transportation system and the startup rate. The design production capacity of the mine is 3 million tons / year, the design annual working days of the mine are 330 days / year, the daily net lifting hours are 16 hours / day, and the daily working shifts are 3 (two shifts for production and one shift for maintenance).
