Abstract (in english)
   The objective of this paper is the evaluation of the influence of basinal structures on the shape of wave patterns of induced seismic events. Vibrations are induced by blasting perations that are practised as a part of exploitation technology. Data set of interpreted wave patterns is collected from data that obtained during experimental measurement in the Nástup Tušimice Mines in the Northern Bohemian Brown Coal Basin in 1996 and 1997. Wave patterns were recorded in the surroundings of the Nástup Tušimice Mines. The duration of wave pattern records was up to 35 s. records of seismic events recorded at the distance from 2 to 5 km exhibit group of body waves duration of which is from 3 to 7 s. The record of the intensive group of surface waves manifesting themselves in a vibration of the harmonic type for 15-35 a follows in the wave pattern records.
   In thos group of waves with the prevailing frequency of about 2 Hz, the maximum recorded value of vibration velocity occurs in the majority of records, too. The wave field that is generated after blasting operations is very complicated. The set of recorded wave patterns from positions with different geological conditions shows influences of basinal structures on the shape of wave patterns
