The Rudna Mining Plant is one of the largest underground copper ore mines in the world. It is the deepest of three mines owned by KGHM Polish Copper JSC in the Legnica-G?og?w Copper District. Copper ores are mined below the depth of 1000 meters. The mine has 1250-meter deep shafts. Rock bursts (the first appeared in 1980) are the greatest threats in the Rudna mine. They are defined as a sudden release of energy which destroys or seriously damages mine workings. The rock-burst hazard have to be combated, mitigated ...

The copper ore deposit in Poland is extracted by three underground mines which belong to KGHM Polish Copper JSC. Since the very beginning, copper ore mining has been accompanied by seismic activity and rock-burst hazard controlled by means of several prevention activities aiming at assessing and combating the danger. Seismology is the prime method to measure seismic activity i.e. the number and energy of rock mass shocks. The hazard monitoring also encompasses measurements of the convergence of mine workings, i.e....
