Abstract: In order to solve the problem of lack of effective monitoring,communication,and protection control in the underground belt conveyor transportation of Tai’an Coal Mine,more comprehensive monitoring information and control methods are needed for its belt conveyor transportation system.By adopting a communication centralized control method combining computer control technology,network transmission technology,programmable logic controller （PLC）,and advanced sensor technology,the collection,display,and alarm of operating data of the belt conveyor transportation system have been achieved.The functions of protection control and telephone communication have improved the automation control performance of underground belt conveyor transportation in coal mines,thereby further achieving the goal of intelligent mining construction of underground multi network integration and emergency linkage in the mine.
