Research on Mine Earthquake Mechanism and Vibration Signal Characters in the Fault

摘要: 断层是影响矿震发生的重要地质因素之一,根据前人的研究成果运用粘滑失稳理论分析了断层处的矿震机理。然后利用SOS微震监测系统,对记录到的某矿断层处的震动信号进行分析,研究了震动波的速度、加速度特征,研究的结果证实了断层处的矿震机理符合粘滑失稳理论。

Abstract: Fault is an important geological factor for mine earthquake.This paper,based on former research,firstly analyzes the mechanism of mine earthquake in fault area with stick-slip instability theory.Then the signal characters of vibration are analyzed in fault area of a certain mine by virtue of the SOS micro-seismic monitoring system,the velocity and acceleration signal characters of seismic wave are analyzed.The result shows that mine earthquake mechanism in fault area conforms to the stick-slip instability theory.
