“…In addition to gas turbines, gas powered engines can also be used in cogeneration schemes for electric generator drive [48,49]. Lower oxygen content in combustion products is the engine feature since air excess coefficient is not more than 2.0-2.2.…”

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

“…Previous studies paid considerable attention to the cogeneration technologies of the energy material production in terms of the operation of mining enterprises [9, 15, 21, 22, 27 -29]. Possibility to apply heat pump generation, wind and solar energy generation, thermal energy use, use of differences in air flow temperature and pressure in the development mine workings, shafts, and on the surface as well as other technological improvements are analyzed in detail [30,31].…”

The paper represents the analysis, which has helped to determine tendencies of the formation of energy resource complex based on the available mining facilities. The approach helps prolong operating life of the mine with the depleted balance reserves or the one being under abandonment. The proposed technologies of generator gas production by anaerobic digestion of organic raw material in the methane-tanks as well as other approaches to the combined formation of new energy systems make it possible to reorient the mine operation. The approach is extremely important for rather depressed mining regions as it helps solve the problem of social strain. Formation of the joint power and chemical production allows both improving economic expediency and preventing negative ecologic impact on surface and underground mine environment. The proposed tendencies make it possible to outline further issues to be highlighted in the following authors’ studies.

“…The coal industry is the leading industry, since coal is the main energy source (Bondarenko, Griadushchiy, Dychkovskiy, Korz, & Koval, 2007;Kuz'menko, Pochepov, & Ryabychev, 2010). Since early 2014, the country's mining fund has suffered serious losses due to the temporary occupation of a significant area in the Donetsk and Luhansk region and conducting warfare, where there are more than 80 mines left.…”

Purpose. Analysis of the man-made mineral formations of ore mining and smelting, fuel and energy complexes development accumulation, location and prospects amount in the Dnipropetrovsk region.Methods. Comprehensive approach, including analysis of state statistics, waste handling sites (WHSs), regional environmental report, environmental passport of the region, as well as data from other information sources is used in the work. Aerial photographs of man-made formations were obtained using the Google Earth 7.1.8 satellite program.Findings. The analysis of the main man-made mineral formations of ore mining and smelting, fuel and energy complexes accumulation in Ukraine (coal and mining industry waste heaps, tailing dumps, ash dumps, smelter slag dumps) was conducted, their amount and occupied areas were estimated. According to the densest location of man-made formations, they are divided into 4 regions: the Prydniprovsk region, the Kryvyi Rih region, the Nikopol region, the Pavlohrad region. According to information sources, the content of some valuable components in man-made formations has been established. Based on the world market prices of technogenic deposits components research, it was proposed to grade them according to the cost of valuable components. The promising directions have been proposed for the use of mineral resources in various economic sectors. It is noted that from the perspective of development of mineral and raw materials potential, the bulk formations are of interest because of their large reserves in the minimum area. But from the perspective of environmental protection and the interests of the Ukrainian people, the bulk technogenic formations occupying significant areas of agricultural land and having smaller mineral reserves are of great interest.Originality. The conception of man-made raw material mineral fund for further industrial development as an alternative to natural deposits is extended and systematized. For the first time, an integrated and detailed analysis has been performed of technogenic waste of the largest waste storage region in Ukraine, as well as the grouping has been proposed of mining and energy sector waste by density of location and by the contained components value. Practical implications.A sketch-map of the man-made objects location was drawn up and their gradation was carried out according to the preliminary prospects of their development. This will provide a more objective approach to the concept of industrial waste development and planning the strategy for the development of mineral and raw materials potential both at the state and regional levels.
