深部巷道围岩协同锚固机理

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+12"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。

The mechanism of synergetic anchorage in deep roadway surrounding rock

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 im-portance to the stability control of the deep roadway surrounding rock, and meets the essential needs of safety production of coal.
