Stress balanced diffusion roadway anchoring method

The invention discloses a stress balanced diffusion roadway anchoring method. The stress balanced diffusion roadway anchoring method comprises the steps that the roadway anchoring range and the lengthof anchor rods and anchor cables are determined; the primary anchoring length, stress and the secondary anchoring length are determined; the positions of anchoring points are determined, the anchoring points have to be arranged in the middle of a roadway roof and the middle of a side part, and the optimal arrangement mode of the anchor rods is a five-flower mode; and the arrangement condition ofa beam strip is that when the width of the roadway is greater than 6 m and the roadway roof is flat, a roadway annular trimmer beam or steel strip is arranged in the middle of the roadway roof, the length of the trimmer beam or the steel strip is sqrt{2}/3 of the roadway width, and as for a fractured formation with the rock mass Protodyakonov coefficient being smaller than 1, the trimmer beam or the steel strip in the tren
