New Wirek Coal Mine
Silesia
It operated between the years 1954–1995 in Kochłowice in Ruda Śląska. There were frequent rock bursts and methane releases there, e.g. in 1995, five miners died due to a rock burst. In the Polish People's Republic, more than 40 blocks of flats, a kindergarten, a casualty department, and six two-family houses were built for the mine's employees.
