The invention discloses a strong-angle span-reducing beam type roadway anchor rod and anchor cable supporting method. A top anchor cable, a vertex angle anchor cable and a top anchor rod which are arranged near a span-reducing point of a roadway top plate, and side anchor cables, side angle anchor cables and side anchor rods which are arranged near span-reducing points of two sides of a roadway are included. The anchor cables and the anchor rods are arranged in the same row, the vertex angle anchor cables are inclined towards the two sides of the roadway, and the inclination angle is 0-30 degrees; the side angle anchor cables incline towards the top and bottom plates of the roadway, and the inclination angle ranges from 0 degree to 30 degrees. According to the strong-angle span-reducing beam type roadway anchor rod and anchor cable supporting method, the anchor cable is regarded as a movable hinged support for supporting the rock beams by utilizing high strength and high rigidity of the ...
