摘要
在详细分析岩爆形成机制和传统经验判据的基础上 ,对岩爆产生条件及其产生部位作了预测 ,并提出了岩爆预防对策 :设计阶段应对洞轴线进行选择、对洞室断面进行优化 ;施工阶段应进行超前应力解除、围岩软化 ,以及采用合理的开挖方式 ;合理选择围岩加固措施 .
Based on the analysis of the conventional criteria for and formation mechanism of rock burst, the conditions under which rock burst takes place and positions of rock burst are predicted. Besides, some countermeasures are proposed for prevention of rock burst, including reasonable determination of the chamber axis and optimization of the chamber section in the design stage, and pre elimination of stresses, softening of adjoining rocks, and reasonable determination of the excavation mode and reinforcement measures in the construction stage.
