The methane hazard is excessive content of this gas in the mining excavations. This is a source of high risk security and continuity of the mine. The Piast–Ziemowit is the only non-methane mine in the Polish Mining Group. In 2015, 66,4% of the coal mined in Kompania Węglowa S.A. mines comes from methane coal seams. Methane drainage is the most effective but very costly method of combating methane hazard.The costs of prevention and eradication of methane hazard is charged to the costs of coal mining. Therefore, performance of methane drainage in the mines of the Polish Mining Group is adapted to the scale of the methane hazard. The article presents an analysis of the costs of prevention of methane hazard for mines with different absolute methane and its impact on the level of these costs.}, type={Artykuły / Articles}, title={Methane hazard and a study of its prevention costs in 2012–2015 on the example of selected mines}, URL={http://www.czasopisma.pan.pl/Content/109827/PDF-MASTER/potoczek-i-inni.pdf}, keywords={methane, methane hazard, the costs of prevention of methane}, }
