Study on Identification of Mine Pressure Bumping Dangerous Sources Base on Geophysical Responses

A mine pressure bumping occurred model was established and the hierarchical Identification idea and the geophysical method of the mine pressure bumping in underground mine were theoretically analyzed and determined.A monitoring and measuring test and study was conducted in Qianqiu Mine with the micro seismic method of the minefield,the earth acoustic method of the coal mining face scope,electromagnetic radiation method of the local dangerous location.The study results showed that the geophysical monitoring and measuring method appeared common features and that was to say that before the mine pressure bumping accident occurred,the warning signs could be monitored and measured with the abnormal micro seismic accidents,the earth acoustic accidents and the electromagnetic radiation accidents.Those information could be the mine pressure bumping dangerous sources identified.From the view of the time,the geophysical method could identify the mine pressure bumping dangerous sources before the mine pressure bumping occurred.From view of the space,the geophysical method could identify the remote,large scope and full dimensional dangerous sources.
