Application research of mine automation system of Kouzidong Coal Mine

In view of problems of construction of current mine automation system, the paper proposed a construction scheme of mine automation system of Kouzidong Coal Mine. Each underground subsystem uses Mincos control system as main control unit. The main control unit collects information of internal sensor though bus of Mincos control system and communicates with controller of matching equipment of each subsystem through Modbus and Profibus, meanwhile, the main control unit communicates with surface centralized control system through Ethernet. The actual application shows that the scheme can provide reliable security for production automation of Kouzidong Coal Mine.
