“…In hard coal mines in the Upper Silesian Coal Basin, PPV measurements in underground mine workings are more common, but they have not been used so far in the selected mine. The seismic energy of tremors E was calculated by a mine geophysics station using a numerical integrating method [33]. The energy of strong tremors, i.e., equal to or higher than 1 × 10 5 J, was verified with the calculations of the Upper Silesian Regional Seismological Network, which belong to the Central Mining Institute in Katowice, Poland [34].…”
