The invention relates to a method and a device for dragging, storing and recycling a crossheading power supply cable of a fully-mechanized mining or full-mechanized caving mining working surface. The device used in the method consists of a reversed loader cable dragging device 4 arranged on a hand piece of a reversed loader, a bearing section cable groove 7 formed in front of the machine tail 9 of a telescopic belt conveyer and a bearing section cable recycling platform 9; a mobile substation is arranged at a crossheading port; a control switch is arranged on the reversed loader; cable sections are connected by a cable connector; the cable dragging device drags the cables under the action of the active displacement of the reversed loader along with the advancement of the working surface; the cables are arranged and clamped in the bearing section cable groove under the action of the active displacement of the machine tail of the telescopic belt conveyer; residual cables are coiled and stored by the bearing section cable recycling platform; and when one cable section is stored, the cable recycling platform recycles at one time. Crossheading cables for the fully mechanized mining or full-mechanized caving mining working surface are electrically dragged, stored and recycled along with the advancement of the working surface without arranging any monorail crane, slipway or hoisting anchor rod. The method and the device have the advantages of simple procedure, labor saving, higher cable moving work efficiency, low cost and convenient assembly.
