Abstract: The skip hoisting capacity of the two stage mine main inclined shaft for the raw coal transportation system in No.9 Mine of Hebi Coal and Electric Power Corporation Ltd.was small.In order to improve the mine raw coal transportation capacity, a new mode steel cord and concave veins belt conveyor was researched and d esigned. .A double row V shaped roller group was applied to make the conveyor belt in trough and the purposes the trough belt was to improve the fraction coefficient bet ween the material and the conveyor during the raw coal upward conveying and to solve the down sliding problem during the coal upward conveying.The results showed that the upward belt conveyor applied in the mine roadway with 28.5° or 29° was successful.Meanwhile the electric control with the frequency converted control technol ogy of the belt conveyor could realize the electric soft start, the frequency converted speed control and the double electric motor power balance.
