随着采矿与地下水电站隧洞的数量、规模及其深度的日益增长,大规模岩爆和煤爆所造成的死亡事故也在上升,有鉴于此,作者研究了许多工程实例,并结合此问题研究了岩石和煤的蠕变扩容与脆性性状。在这些现场和实验室研究结果的基础上,作者提出了蠕变扩容理论(1981~1983)和简化的脆性破坏理论。用这些理论分析了南盘江天生桥压力隧洞中准稳定的潜在爆裂危险区和声发射区,以及一层告急的煤层;用简化的脆性破坏理论,能够估计煤矿中垂直劈裂区的扩展和研究注水的影响。在这些理论概念的基础上,作者提出了一些对岩爆和煤爆进行定位、预测和缓解的实用方法。
With the increasing number, scale, and depth of mining and underground hydropower tunnels, the fatal accidents caused by large-scale rock bursts and coal explosions are also rising. In view of this, the author has studied many engineering examples and combined this with the research. Rock and coal creep expansion and brittleness properties. Based on the results of these field and laboratory studies, the authors proposed creep expansion theory (1981-1983) and simplified brittle failure theory. These theories were used to analyze the quasi-stabilized potential burst danger zone and acoustic emission zone in the pressure tunnel of the Nanpanjiang Tianshengqiao, and a layer of emergency coal seam; the simplified brittle failure theory can be used to estimate the expansion and study of the vertical split zone in coal mines. The impact of water injection. Based on these theoretical concepts, the authors proposed some practical methods for locating, predicting, and mitigating rock bursts and coal bursts.
