The study is conducted to assess the geological and technological parameters that affect the prospects for the development of methane-coal deposits and ensure efficient and economically feasible extraction of methane from coal seams. This study uses methods to analyze geological data and the physical and chemical properties of coal seams and to examine the technologies and economic aspects of methane extraction from coal seams. The study includes an assessment of industrial methane production from coal seams using international practice and a comparative analysis of the geological characteristics of deposits in accordance with international standards. Geodynamic features of coal structures affecting the formation of natural cracks and reservoir permeability were considered, as well as the potential use of artificial methods to increase permeability and improve gas production processes. In this study, modern views on the relationship between methane and coal are presented based on theoretical and experimental data from physical chemistry and studies on the properties of sorbents. It is identified that gas permeability through coal seams depends on their general structure, pressure fluctuations, and special pressure dynamics of rocks. Moreover, it was determined that intact coal seams exhibit permeability dependent on the integrity of the formation. The importance of developing modern methods of methane extraction in accordance with environmental and energy standards was emphasized. In particular, the Karaganda basin has become a promising region for methane extraction initiatives, given its geological characteristics. The results of the study provided valuable information for the development of effective strategies for extracting methane from coal deposits, which will contribute to improving the environment, increasing energy sustainability, and reducing dependence on traditional energy sources.
