Abstract：By using the observation data of mining earthquakes occurred from November 2004 to March 2009 in a coal mine of Yanzhou，Shandong province recorded by the seismic network，the sources of mining earthquakes are located and the following questions are studied：methods of improving the accuracy of mining earthquake source location；relationship between distribution of sources of mining shock and the tectonic background；relationship between large mining earthquakes and the in-situ ground stress；relationship between mining earthquakes and the process of mining；relationship between the mining shock and the disaster event that envelop wall is destroyed；the law of seismicity of mining earthquakes series. The primary results are obtained as follows：by using the methods of polarization analysis and wave form correlation analysis，the source location accuracy can be improved under the condition of sparse networks. The results show that it is the mining shock that made the top tray near the residual column of coal rake collapse and then formed strong blast that destroyed the envelope wall. It is also shown that the three component seismometer and wave form analysis have important effect in diagnosing the properties of mining disasters.
