Study on the mechanism and application of synergistic anchoring systems in roadway surrounding rocks

Abstract：In order to study the multiscale and multilevel cooperation and contradction among the control variables,which are inherent in anchoring the surrounding rocks,and to investigate the laws of the consequent system evolution,a train of thoughts concerning the research on the synergistic anchoring system in surrounding rocks was presented.Taking the approach of synergistic principles and methods,this paper discussed the structure of the synergistic anchoring system in surrounding rocks from the aspect of its connotation,basic features,and system constitution,and then defined the major contents of this research,its research ideas and methods.On this basis,this paper concentrated on the synergism in the anchoring system and the synergistic mechanism between the anchoring system and its surrounding rocks,and worked out the general procedure,content and method of synergistic anchor designing.This research proves that the synergistic anchoring system stresses both the macroscopic and the microscopic coordination and optimization of the sub-systems.By means of synergism,it achieves an overall performance greater than a simple sum of all sub-systems and elements.Therefore,it is a controlling mechanism and technique with a capacity of optimizing the part and enhancing the whole,which fulfills the ultimate requirement of controlling and stablizing the roadway surrounding rocks.
