Abstract

On January 25, 2018 within the limits of the Vorkuta urban district, the regional seismic stations recorded an event classified as a rock burst. The records of 17 stations at the epicentral distances from 260 to 1645 km were collected and analyzed. The epicenter was localized in the Komsomolskaya Mine field of the Vorkuta coal deposit. Parameters of this event hypocenter were calculated by the data of the mine seismic monitoring network GITS, Vorkutaugo, which greatly improved reliability of determination of the hypocenter as compare with processing results of he regional stations and offered a reference estimate of the localization. January 25 rock burst has one more time proved that the geodynamic control and safety enhancement in the important mining region in the Republic of Komi requires installation of seismic stations nearby mine fields in the Vorkuta district.
