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

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.
