Abstract (in english)
   The submited article contains measurement result of the convergence of mine opening on the mine Mayrau (Kladno coal district), carried out in connection with the research of induced seismic phenomena. Potentiometric distance sensors were used for the measurements and the measured data were recorded on a surface PC. Two measurement sites were used to check the convergence rate and value and namely their affecting by induced seismic events, recorded by the local seismic network. A very pronounced effect of significant seismic phenomena, on the course of convergence, could be established. However, the convergence measurement results did not have any prognostic character, because they were affected always simultaneously with the occurrence of a seismic event. However, these measurements enable the correctness of the determination of localiton of induced seismic event foci to be confirmed or, eventually, they may draw the attention to eventual errors in their location
