157 However, the issue of VAM reduction, if not soon, will certainly sooner or later also affect coking coal mines, and thus JSW S.A. In the assessment of the impact of the regulation and during discussions with representatives of the European Commission, it was pointed out that there are already installations in operation around the world for the utilisation and economic use of methane from VAM ventilation air, but none of these installations operate in the European Union under European Union market conditions and applicable regulations. Jastrzębska Spółka Węglowa does not ignore the problem of methane emissions from ventilation air, quite the contrary. In addition to extensive market research and the search for business partners, we are participating in the ProVAM research project. The main objective of the project is to examine the conditions in the ventilation shafts of Polish and Romanian mines, review the available VAM technologies and check the possibility of installing VAM utilisation units in European hard coal mining conditions. A key aspect that was examined was Plant Shaft Average air flow [m3/min] Average methane concentration 2021 2022 2023 2024 2021 2022 2023 2024 "Borynia" Site # III 25 660 26 783 26 398 24 878 0,06 % 0,10 % 0,07 % 0,06 % # VI 11 712 12 829 14 487 13 578 0,23 % 0,13 % 0,10 % 0,10 % "Budryk" Mine # II 19 780 19 660 19 257 19 526 0,29 % 0,19 % 0,33 % 0,21 % # V 16 190 15 706 14 687 9 764 0,25 % 0,35 % 0,27 % 0,35 % "Knurów" Site "Aniołki " 7 741 8 250 7 063 7 521 0,08 % 0,08 % 0,31 % 0,16 % # V 12 393 12 996 10 192 9 863 0,02 % 0,06 % 0,13 % 0,06 % "Pniówek" Mine # III 19 921 18 954 20 166 18 716 0,12 % 0,12 % 0,10 % 0,13 % # IV 10 758 10 768 10 825 10 713 0,34 % 0,35 % 0,41 % 0,34 % # V 14 845 14 329 13 492 12 660 0,32 % 0,33 % 0,33 % 0,33 % "Szczygłowice" Site # IV 13 950 9 238 9 200 8 963 0,31 % 0,20 % 0,20 % 0,32 % # VI 19 900 16 624 16 740 17 013 0,36 % 0,27 % 0,34 % 0,41 % "Zofiówka" Site # IVz 11 920 11 930 12 242 18 623 0,08 % 0,07 % 0,08 % 0,13 % # Vz 29 810 28 441 28 605 28 173 0,11% 0,35 % 0,29 % 0,21 %
