The Lubin Copper Basin is a source of induced seismic events of considerable size. The paper presents the source mechanism study of fifty seismic events from Rudna Copper Mine that occurred in 2007. The energies of studied seismic events were greater than 105 J. Focal mechanisms for those events have been calculated with seismic moment tensor inversion method using FOCI computer software. The calculations were made using L1 and L2 norms. Final results are presented for L1 norm due to its lower sensitivity to possible errors. Spectral analysis of P and S waves was also performed. The analysis shows that typical focal radius is of about 200 m
