Abstract: The volume of methane accumulates in the carboniferous rock mass is estimated to be over 102 billion m³. In 2018, the extraction of methane from the carboniferous series in the Upper Silesian Coal Basin (Poland) amounted to 320 million m³, which corresponded to the quantity of the gas obtained via the hard coal mine methane drainage system in the entire USCB. The Regulation of the European Parliament and of the Council on methane emission reduction in the energy sector introduced on 15th December 2021 obligates the mining industry to record the methane emission volumes in active mining plants as well as to identify and record the methane emission volumes in decommissioned mines. In this paper, the methodology and the associated measurements for determining the uncontrolled methane emissions through the carboniferous overburden in an area of decommissioned mines in the Upper Silesian Coal Basin were proposed.

Keywords: uncontrol methane emission; coal mine; risk analysis; decommissioned mines.
