The actual calculation data and tension curve for belt conveyer for main incline shaft in certain mine indi-cate the effect of central drive method on the belt and motor selection of large-scale main belt conveyer.Through comparison of advantages and disadvantages of three common soft start modes including CST,variable speed fluid coupling,and varia-ble frequency starting mode,the variable frequency starting mode shows outstanding overall advantages.By referring to and applying Harrision Curve and Dodoge Curve,both the speed and acceleration curve at start is given through actual exam-ples.At last,attention shall be paid to certain problems in central-drive belt conveyer by examples.
