- Since the beginning of the 1990s, there has been an intensive restructuring of hard coal sector in Poland. In this process, successive mines are being decommissioned, most of which are characterized by considerable methane content. The vast majority of hard coal mines in Poland, including all the mines belonging to Jastrzębska Spółka Węglowa S.A. are highly methane mines. This means that the air flowing out of the mine shafts contains a certain concentration of methane, the size of which depends on the amount of air and the amount of methane-filled air, which is emitted into the mine excavations. In 2019 alone, nearly 807 million m3 of methane was released from the rock mass affected by mining, out of which only 195.6 million m3 were used economically. This publication presents and characterizes projects involving the extraction and economic use of methane from both active and decommissioned mines. The paper also points out the legal and administrative conditions in which projects related to methane extraction and utilization can be implemented. The paper presents measurable benefits from demethylation not only in terms of improving the safety of coal extraction, but mainly economic and ecological aspects. Above all, attention was paid to the fact that the vast majority of methane was irreversibly emitted to the atmosphere to the detriment of the natural environment.
