Entwurf elektromagnetischer Antriebe,e 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.

,Die Maxwell’schen Gleichungen,s applied for an explanation of fractures influence on the seismic wave propagation. According to this theory, the fracture stiffness can be assessed on the basis of velocity directional dependence. The measurements made proved experimentally the validity of this approach, specifically for the frequency interval from 500 Hz to 700 kHz.

Frictional Metamorphism of Coal in the Upper Silesia Coal Basin, Southern Poland,ers tested. The mean values of the coefficient of variation for all of the tested parameters ranged from 1 to 100%; the average value was 16.6%, and changeability compared to the unchanged zone varied from 0 to 51.5%. These changes are connected with flexible faults whose run is close to N-S and W-E directions.

Magnetostatische Felder I (Vakuum),e longwall face under study. The GPS data were also used to determine the maximum surface subsidence velocity (MSSV) in the trough area and to assess the approximate time of occurrence of maximum surface subsidence velocity (MSSV average time). Finally, the relations between subsidence parameters and seismic activity were sought.
