Abstract: The article deals with the issue of the release of methane from coal seams and its emission to the atmosphere from the mines of Katowice Coal Holding Company in the years of 1997-2011. This period is characterized by organizational changes in Polish mining industry involving liquidation or a merger of mines, an increase in both the concentration of coal mining activity, and the depth of the exploitation at which the amount of methane in coal seams grows ever larger. The analysis of the variation in the methane emission from the coal mines in that period points out a decline in the intensity of the emission until 2005, probably owing to the liquidation of some mines, later, but in the years of 2006-2010 - a considerable increase in both the absolute methane emission of the mines and the methane emission to the atmosphere despite a dropping coal extraction. This signifies that mining activity takes place in increasingly difficult gas conditions prevailing at great depths. Despite a slight decrease in both the absolute methane emission and methane emission to the atmosphere in 2011, a continuously growing trend of this phenomenon should be expected in the future. A similar tendency is also visible in the whole Upper Silesian Coal Basin, however the methane emission peak falls in 2008. In order to curb the growth of the amount of the emitted methane, it should be commercially utilized. Particularly vital is considering methane as an unconventional resource, following the example of other countries.
