Opis:: Abstract Methane production from natural gas hydrates will enable the reduction of a great part of natural gas import deliveries and to give up them completely in the future. Gas hydrate technologies compared with existing ones, also gives the possibility to transport gas, divide gas and liquid mixtures, concentrate water solutions, utilize and store СО2, etc. with greater efficiency. However, methane production technologies have not developed industrially and their study was performed with the help of experimental units and in separate gas hydrates deposits in the mode of tests and elaborations. The prospects of the hydrate technologies development in the Ukraine were determined: transportation of natural gas in the form of hydrates, long-term storage of natural gas in hydrate state, natural gas production from its hydrate deposits. Positive international experience in terms of the development of hydrate technology is studied. In order to study formation and dissociation hydrates of carbon dioxide and natural gas components, Gas Institute have made hydrate stand facility. The express method of determining thermodynamic and kinetic parameters of hydrate transformation was tested. Natural gas hydrates as well as carbon dioxide hydrates were produced with the help of the express method. It was determined that the composition of original natural gas and gas of hydrates decomposition is of great difference – it means that “selective” hydrates formation of natural gas formation is performed.A set of experiments was also performed to study the process of methane replacement with the help of carbon dioxide. According to the gaseous phase analysis, 14% increase of methane content was fixed. This fact proves its replacement in hydrates with the help of carbon dioxide.

Tytuł:: Methane emissions in selected hard-coal mines of the Upper Silesian Coal Basin in 1997–2016

Opis:: Hard coal is extracted in the Upper Silesian Coal Basin (USCB) from deeper and deeper coal seams every year. In 2000, the average depth of coal extraction was 600 m, in 2010 – 700 m, but in the last two years (2016–2017) this has been extended to a depth of 770 m. The USCB is not homogeneous in layout in terms of methane hazard, but rather very diverse. Therefore, the USCB has been divided into seven gassy regions to show differences in methane danger distribution. Northern and central USCB regions (I, II and III) are the mostly naturally degassed, so the most dangerous gassy conditions are in the IV and V regions, where methane content in coal seams varies from 6 m3/Mg coaldafto above 18 m3/Mg coaldaf. The two westernmost USCB gassy regions (VI and VII) are poorer in methane than the IV and V areas. Six representative coal mines were chosen: Mysłowice-Wesoła, Budryk, Brzeszcze, Pniówek, Marcel and Rydułtowy-Anna based on their high hard coal production and total methane emissions. The reason for the highest methane emission in those regions might be fault tectonics facilitating methane migration and also the thick and continuous Miocene cover constituting a hermetic screen for gases in the southern part of the USCB.

Tytuł:: Changes in the methane emissions and hard coal output in the Brzeszcze mine (the Upper Silesian Coal Basin, Poland)

Opis:: The paper presents the variability of methane emissions in mining excavations in the Brzeszcze mine (Poland) against the background of hard coal output, geological and mining factors. The geological structure of the Upper Silesian Coal Basin (USCB) is very diverse. The Brzeszcze coal deposit is located close to the large and permeable Jawiszowice fault which increases the methane hazard during mining activities performed close to this fault. The overall decrease in hard coal output (1988–2018) has coincided with a rapid increase in methane emissions (1997–2018). Throughout the study period, hard coal output decreased threefold from 3.9 to 1.2 million Mg annually. Coal extraction in high methane content beds (e.g. 510, 405/1, 364, 352) increases the total methane (CH4) emission into mining excavations, aggravating the methane hazard due to the high explosiveness of the gas. To protect miners, coal workings need to be continuously ventilated, taking the harmful gas out of the mine (ventilation air methane emission) or methane needs to be captured by underground methane systems (degassing). Every year, over 34 million m3 of CH4 is captured by the drainage systems and over 70 million m3 CH4 (average) is discharged through ventilation shafts into the atmosphere. The presence of the large, permeable regional dislocation, the Jawiszowice fault zone, shaped the methane concentration in the fault vicinity, when the highest methane emissions during coal mining was studied.
