引入地震力学中库仑破裂应力变化的概念,对断层冲击地压的形成机制进行理论分析,并进行简单的数值模拟计算,认为开采扰动引起断层附近应力场变化,可能使断层面更加稳定,也可能使断层面因失稳而产生活动,引发矿震。这项工作为地震力学应用于矿山灾害研究提供了一些思路,同时也指出,对于确切的矿山地震的发生机制,仍有很多工作要做。
The concept of Coulomb failure stress in seismic mechanics is introduced to theoretically analyze the formation mechanism of fault rockburst and carry out simple numerical simulation. It is considered that the change of stress field near the fault caused by mining disturbance may make the fault plane more stable, The fault surface instability caused by activity, triggering mine shock. This work provided some ideas for applying earthquake mechanics to mine disaster research. At the same time, it pointed out that much work still needs to be done for the exact mechanism of mine earthquake.
