摘要
通过对深部采矿扰动诱发深部围岩发生流变、岩爆造成巷道变形破坏的机理进行描述,突显了采矿扰动对深部岩体应力应变发展不可忽略的影响。从安全生产的角度,结合深部岩体的特性,在分析基础上对深部开采中巷道维稳和扰动控制方面提出了建议。
By the introduction on mechanism of rheology and rockburst in deep surrounding rock induced by the deep mining disturbance, resulting in deformation and failure in tunnels, the paper shows the important effects of mining disturbance on deep rock stress and strain. In view of production safety and combined with the characteristics of deep rock, recommendations based on analysis about tunnel stability maintenance and disturbance control in deep mining were made.
