Since strong seismic events are connected with rockburst hazard, it is a continuous requirement to reduce seismic risk. One of the most effective methods to do so is blasting in potentially hazardous mining panels. In this way, small to moderate tremors are provoked and stress accumulation is substantially reduced. In this paper we present an analysis of post-blasting events using Full Moment Tensor (MT) inversion at the Rudna mine, Poland, underground seismic network. In addition, we describe the problems we faced when analyzing seismic signals. Our studies show that focal mechanisms for events that occurred after blasts exhibit common features in the MT solution. The strong isotropic and small Double Couple (DC) component of the MT, indicate that these events were provoked by detonations. On the other hand, post-blasting MT is considerably different than the MT obtained for strong mining events. We believe that seismological analysis of provoked and unprovoked events can be a very useful tool in confirming the effectiveness of blasting in seismic hazard reduction in mining areas. date: 2015-10 date_type: published publication: Contemporary Trends in Geoscience volume: 4 number: 1 publisher: De Gruyter Open id_number: doi:10.1515/ctg-2015-0003 issn: 2299-8179 official_url: http://doi.org/10.1515/ctg-2015-0003 access_IS-EPOS: limited owner: Publisher citation: Caputa, Alicja and Talaga, Adam and Rudzinski, Lukasz (2015) Analysis of post-blasting source mechanisms of mining-induced seismic events in Rudna copper mine, Poland.
