Item type:Article, Access status: Open Access , Zagrożenie sejsmiczne w rejonach eksploatacji rud miedzi sąsiadujących ze strefą uskokową Rudnej Głównej(Wydawnictwa AGH, 2010) Burtan, ZbigniewSeismic hazard is one of the major risks faced in the Polish copper mining sector. Factors responsible for generating high-energy shocks include the tectonic features of the deposit being mined, manifested mainly by dislocations of considerable thrust. Experience gathered to date shows that mining in the region of major tectonic disturbances might lead to high-energy tremors and often rock bursts, when the faulting activity is enhanced. The study explores the tectonic features in the copper mines of the Polish Copper Holding KGHM Polska Miedź S.A., revealing major thrusts and large extents of the faulty zone in the mining area. The fault zone in Rudna Główna is most characteristic of faults encountered in KGHM Holding mines in the mined- out regions, hence this study uses that example to show the registered seismic activity and explore the potential impacts of mining operations. Development of the seismic hazard in the areas adjacent to the fault zone in Rudna Główna reveals the major risk of high-energy tremors and, potentially, of major rock bursts as well.
