The invention discloses a moving method of a belt conveyor. A plurality of racks of the belt conveyor are fixedly connected with two parallel steel rails on two sides of the racks; a cable hopper truck stretches over one end of the belt conveyor and is arranged on the steel rails; a sledge is arranged below the belt conveyor; a first rack group and a first rail section below the cable hopper truck are disconnected from the rest rails and the rest steel rails separately; the cable hopper truck and the first rail section are fixed on the sledge; the moving method comprises the following steps: first driving equipment is utilized to move a second rack group and a second rail section by one step; second driving equipment is utilized to drive the sledge to move the first rack group, the first rail section and the cable hopper truck by one step; and all the steps are circulated. According to the invention, the delay phenomenon caused by self-propelled moving of the cable hopper truck is avoided, so that the moving efficiency is increased by 200%, and the break-off and expansion bend phenomena of the steel rails during the moving process of the belt conveyor are avoided.
