A large-diameter anchor cable for a mine is composed of a cable body, an anchor, a support plate and a stirring connector.The cable body is composed of a cable body steel wire, a head rigid core tube, a flexible core tube, a tail rigid core tube, a choke cable band, a cable band, a head cable band, a guide cable end and the like.The external diameter of the cable body is phi 30-50 mm; the head rigid core tube, the flexible core tube and the tail rigid core tube are located in the center of the cable body and connected in sequence; the core tubes can be replaced by a head rigid core rod, a flexible core rod and a tail rigid core rod correspondingly.The external circumference of the cable body resin anchorage section adopts a cable band type or expanding ring type or steel wire wrapping type expanding structure to expand the diameter of the cable body resin anchorage section and reduce a diameter difference between the cable body and a drill hole, and the stirring effect and the anchoring force of resin are improved.The resin anchorage problem of the large-diameter anchor cable is solved for applying the anchor cable to a non-coal mine.Large-diameter anchor cables with different diameters can be processed by means of existing high-strength steel wires according to site requirements.
