System Research in Energy| Zusammenfassung: | A new methodology for ranking coal mines by the integral coefficient of prospects has been developed. Unlike the known ones, the developed methodology uses a system of volumetric, technological, financial, economic, safety, environmental and social criteria for the functioning of coal industry enterprises that are accessible to the general public. These criteria have been brought to a comparable form. The methodology also takes into account the degree of importance of each criterion in terms of its impact on the technical and economic level of the mine. The system of criteria for the prospects of coal mining enterprises includes the following: installed production capacity of mines, coal production volumes, coal production volumes using new technologies, the cost of coal products, the category of mines by sudden coal and gas emissions, the number of employees and the number of residents of the community where the mine is located, and methane emissions. Mine ratings were calculated to identify unpromising mines that will be considered for further operation or closure. The calculations took into account the WTO requirements for the prospects of coal mining enterprises, as well as the consequences of military operations in Ukraine. The mines were analyzed for two areas of coal product use, namely for energy and coke production. The developed methodology allowed us to form a list of promising coal mining enterprises for steam and coking coal production. The research results provide an opportunity to make managerial decisions on further operation or closure of unpromising coal mining enterprises when developing forecasts of coal fuel supply for thermal power and the country's economy as a whole. The decision on the feasibility of further operation will be made for mines of the lower group. |
