Abstract : The paper presents the results of studies of fault zones carried out in the Upper Silesian Coal Basin. Three types of changes of the coal were distinguished: degradative changes connected with a deterioration in the quality of the coal; aggradational changes connected with an increase in the quality of coal; and the type of coal which shows no significant change in the values of its parameters. Hypergenic changes of the coal were mainly observed in the fissures of faults with the dominant strike in NW-SE and NE-SW directions. The faults of such parameters in the USCB are characterized as fragile. They were formed in the period of the inversion of the USCB, in a tensional stress regime. Aggrading changes of coal were observed in the faults planes with the dominant strike in NNW-SSE and W-E directions. The faults of such a run in the USCB are susceptible in nature and developed during the compressive regime. In the fault zones where no changes were in the coal quality, the orientation of faulting surfaces did not show the privileged run direction.
