Abstract: This article designed to clarify the importance of vibration observation in colliery safety. Many coal mine Disasters have occurred in recent years. At present gas content monitoring is widespread in our country, but vibration observing methods are rarely used. In fact, major coal mine disasters, such as gas explosions, flooding as well as mine quake, are closely related to coal rock crack phenomena. Of course, the crack will necessarily cause a vibration. Therefore, studying various vibrations is an important and effective way to study and prevent mine disasters, this paper also briefly introduced some researching results as well as some monitoring and researching methods in this aspect.
