1320 converted into hydrogen, and the resulting CO₂ use in fire prevention. This will allow 100% utilisation of methane currently captured at methane drainage stations, thereby meeting EU methane regulations. Project REM (implementation 2023÷2027) - „Reduction of methane emissions from post-mining goaf in order to minimise its flow into the ventilation air VAM”, the purpose of which is to determine possibilities of obtaining methane from post-mining goafs of an active mine and implementing a methane removal system for reduced methane concentration in the captured gas. The world's first innovative installation to reduce methane emissions from closed areas of an active mine will be built at KWK „Pniówek” (JSW SA). Methane obtained from post-mining goaf will be used to produce electricity in specially designed gas engines connected to power generators. The solutions tested in this project will ultimately be implemented in all JSW SA mines. Methane emissions into the atmosphere from mine ventilation shafts will be monitored and verified using the latest optical gas indication (OGI) technology and unmanned aerial systems (UAS). Thus, an innovative, comprehensive management approach for the post-mining methane emission chain can be successfully applied to any coal methane mine characterised by a multi-bed. Project MEMO (implementation 2025÷2029), which aims to develop robust methods that will be applicable in all European Union countries for precise emission inventories of methane. This includes classifying closed mines for methane emission potential, defining methods using Union-specific emission rate estimation and assessing the feasibility of precisely measuring the methane emission flux to 0,5 t/year. Currently, the following projects are being implemented at the Central Mining Institute - National Research Institute: - Methodology for determining the location of uncontrolled methane emission zones and their limitation in areas post-mining (implementation 2024-2026), the aim of which is to develop an integrated method for determining the location of zones of uncontrolled methane emissions along with measurement of the amount of methane emissions in areas of liquidated mines using modern measurement techniques (satellite measurements, UAV and atmospheric chemical measurements), - Principles for the liquidation of hard coal mines in terms of reducing methane emissions into the atmosphere (implementation 2024-2028), which involves developing principles for the liquidation of mine workings, which, when implemented in mining practice, will reduce methane emissions into the atmosphere from mines being liquidated and those planned for liquidation and mining movements. In addition, the following research projects were carried out at the Central Mining Institute - National Research Institute, in cooperation on a consortium basis with foreign scientific units and domestic coal producers: - project AMMUSCB (implementation 2019÷2023, co-financed by the European Development Fund Regional), which involved designing and testing the technology for capturing methane and its use for energy or heating purposes by making a hole from the surface to several goaf spaces located in seams at different depths, thus increasing the efficiency of methane intake through a hole compared to classical methane removal. - project DD-MET (implementation 2019÷2023, co-financed by the Coal and Steel Research Fund), which concerned the development of an innovative methane drainage technology using long-range directional holes made above the exploited coal seams, - project SilesiaFrac (implementation 2019÷2021, co-financed by the European Development Fund Regional), concerned the development of innovative hydraulic fracturing technology, rock mass technologically advanced fracturing fluids, allowing for minimising damage to the rock matrix to limit methane leakage into mine workings, - project Went-Met (implementation 2018÷2021, co-financed by the European Regional Development Fund), which consisted in developing the innovative catalytic–adsorption base technology MARCO (Methane Adsorber Regenerative Catalytic Oxidation) by adapting it to the process of eliminating methane from mine air and enabling energy recovery on an industrial scale, - project METHENERGY PLUS (implementation 2017÷2020, co-financed by the Research Fund Coal and Steel), which allowed the development of methods to increase the efficiency of recovery and use for energy and chemical purposes of the ventilation methane captured in active and closed coal mines.
