针对深部巷道围岩控制过程中遇到的难题,以协同论为理论基础和方法指导,在前期研究和工程实践的基础上,提出深部巷道围岩协同锚固机理。通过分析巷道围岩控制系统的组成因素,介绍协同论对围岩锚固的描述方法,提出结构协同、强度协同、刚度协同、锚固时机协同、预紧力协同、变形协同等协同作用机制,以此初步建立协同锚固机理的研究框架。研究表明,协同锚固系统在宏观整体功能大于各子系统之简单总和,即产生“1+1>2”的协同增强效应,这对于深部巷道围岩稳定性控制来说是最为根本和至关重要的,也更加符合煤矿安全生产的本质要求。
Aiming at the problems encountered in the control of surrounding rock in deep roadways, the synergetic theory is taken as the theoretical basis and method guidance. Based on the previous research and engineering practice, the cooperative anchorage mechanism of surrounding rock in deep roadways is proposed. Through the analysis of the components of surrounding rock control system, this paper introduces the method of describing the anchoring of surrounding rock by the synergetic theory and puts forward the synergetic mechanism of structural synergy, strength synergy, stiffness synergy, anchor timing synergy, prestress synergy and deformation synergy. Preliminary establishment of collaborative anchoring mechanism of the research framework. The research shows that synergistic anchoring system has a synergistic effect of increasing the overall macro-scale function over the subsystems, which is the most fundamental to the stability control of surrounding rock in deep tunnels. Crucial, but also more in line with the essential requirements of coal mine safety in production.
