✦ Synopsis

Six mining tremors (connected with rockbursts) from the Wujek coal mine area, with energies lo'-10' J, were chosen for investigation. All events caused serious and well documented damage in mining excavations and were felt on the Earth's surface. The mechanisms of these tremors were determined on the basis of digital recordings from the mining seismological network using the seismic moment tensor inversion method for P-wave first arrivals. The number of analysed events was small but it appears that tremors connected with coal rockbursts have a smaller isotropic to deviatoric ratio of the seismic moment tensor compared to mining tremors without damages observed underground.
