Abstract: The aim of this paper is to present the results of an investigation of induced seismic events which occurred during mining in
the coalfields of Plants Paskov and Staříč of the Paskov Mine which belong to the southern part of the Ostrava-Karviná coal
mines. Some results obtained in the time period January 1992 – December 2002 have already been published, and therefore,
are mentioned here only briefly. The paper is based on new results of seismological observations at the OKC, KLOK, STEB
seismic stations operated by the Institute of Geonics AS CR and stations of the Green Gas DPB, a.s., Paskov. A total of
26 seismic events were monitored from January 2008 to February 2012, most of them were localized into the area under
study. As for the energy span of individual events according to the energetic classification of the Geophysical Centre of the
Green Gas DPB, a.s., Paskov, all seismic events in Table 1 were estimated within the limits E(J) <5.0 ×102 / 2.0 x 104 >. |
