建立了断层冲击地压发生模型,将断层冲击地压的发生看作是静载荷和动载荷的叠加耦合作用,结合冲击地压启动理论和弹性波理论,推导了采掘诱发断层冲击地压发生的能量判据。结合实际工程实例,采用微震监测技术观测某矿1302工作面的微震活动,结果表明微震能够监测到采动应力和断层活化情况,为工作面冲击危险区的确定提供可靠帮助。
The model of rockburst is established, and the occurrence of rock burst is considered as the superposition coupling of static load and dynamic load. Combined with the theory of rockburst and the theory of elastic wave, it is deduced that the mining-induced rock burst pressure Energy criterion. Combined with practical engineering examples, microseismic monitoring technique was used to observe the microseismic activity of 1302 working face of a mine. The results show that microseism can monitor the mining stress and fault activation and provide reliable help for the determination of the impact danger zone of the working face.
