Abstract: According to the design and project practices of the belt conveyor in a dip of No.4 mining block in Wutongzhuang Mine, the paper had a discussion on th e factors considered in the driving method selection of the powerful belt conveyor under the complicated performances.A detail comparison and selection was conducte d on the advantages and disadvantages of the CST, valve controlled speed regulating hydraulic coupling and frequency converted control soft driving modes available a pplied at home and abroad.The paper held that the valve controlled speed regulating hydraulic coupling could meet the driving requirements of the large power, long dis tance and complicated belt conveyor.The practices showed that the control start accelerated speed, start torque, automatic power balance, heat radiation and others we re excellent.
