Through analyzing the components of the controlling system of the roadway surrounding rock, and introducing the way how synergetics direct the anchorage of surrounding rocks, a research framework has been built to propose the synergetic mechanisms concerning structure, intensity, rigidity, anchorage timing, preload, and deformation. The study shows that the synergetic anchorage system achieves the effect of 1+12, as its macroscale function outweighs the sum of its total subsystems. T
