The mine, operated by KGHM , is one of the largest copper mines in Europe and has been in operation since 1974. “The rescue operation is taking place without a pause,” KGHM’s Chief Executive Radoslaw Domagalski-Labedzki told in a news conference. Rescuers can see one of the missing miners but have no contact with him yet and do not know what condition he is in. The earthquake took place at 20:09 GMT on Tuesday, was very strong and caused extensive damage. The epicenter was situated 1500 meters below the surface and had a magnitude of 3.4. Government’s spokesman Rafal Bochenek said Prime Minister Beata Szydlo was heading to the mine on Wednesday. KGHM vision of their goal, known from their website, is about “mine that is safe, profitable, and environmentally responsible.”Underground activities are in big danger when earthquakes occur.
