Ocena istotności wpływu transferu naprężeń statycznych wywołanych przemieszczeniem kosejsmicznym wstrząsów górniczych na proces sejsmogeniczny w kopalniach

Abstract

We investigated an effect of static stress transfer for the mining-induced seismicity from Rudna Mine. We consider events of energy over 10$^{5}$J, which occurred in Rudna Mine from 1993-2006. We examine the possible triggering checking correlation between event locations and the stress-increased zones. We find that more than 50% of the analyzed seismic events occurred in areas where stress was enhanced due to the occurrence of previous events. Statistical test proved that for stress changes from 0.02 bar static stress triggering in Rudna Mine exists and this effect is statistically significant at the 95% confidence level.
