Abstract: In response to the difficulties during the surrounding rock control in deep roadway, based on previous research and engineering practices, the mechanism of synergetic anchorage in deep roadway surrounding rock has been put forward, taking synergetics as its theoretical basis and guideline. 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+1>2, as its macroscale function outweighs the sum of its total subsystems. This is of fundamental and vital importance to the stability control of the deep roadway surrounding rock, and meets the essential needs of safety production of coal.

Key words: deep roadway, synergetic anchorage, mechanism of function, synergetic effect
