in time and fully used, as international experience shows. Responsibility and financial costs for restructuring in most cases rested on the state itself, without taking into account the internal enterprises capabilities [4]. The following six main models of such repurposing can be separated: - objects of industrial tourism – usually these are conserved mines and factories, which give an opportunity to feel the spirit of the industrial region; - technological parks – on the territory or in the buildings of the former industrial facility, thematic clusters of small and medium-sized businesses development – technological and scientific startups are created; - cultural centers – cinemas, theaters, concert halls, galleries in the premises of former enterprises; - a sports complexes – equipped platforms and walls for rock climbers in the buildings of former factories, a school of divers in a gasholder filled with water or a ski track on the tericon slope; - a commercial objects – restaurants, entertainment facilities or a shopping center; - further usage in industry – transport and logistics centers of international corporations or for the creation of capacities from highly maneuverable generation, which are badly needed for Ukraine. Scientists from the Institute of Geotechnical Mechanics of the National Academy of Sciences of Ukraine believe [5] that, taking into account the specifics of mining production, the most rational energy orientation of such solutions, namely the repurposing of coal mines into low-power thermal energy complexes (LTEC) for the processing of local cheap coolants, high- ash coal, mine methane, coal beneficiation waste intended for the combined production of heat and electricity. This idea combines within the framework of a single mining and energy complex the processes of extraction of carbon-containing raw materials and their processing into thermal and electrical energy with the simultaneous elimination of the absolute majority of intermediate technological operations, which open up the possibility of significantly increasing of economic efficiency, environmental cleanliness and safety of the entire complex works, and the generation of electricity based on heat consumption allows to reach a fairly high efficiency – about 80%, which is impossible today for potent power plants. Depending on the energy- consuming infrastructure of the region, the power of the complex can be chosen from 5 MW or more. Most of the national energy systems (including UES of Ukraine) were built on the principles of large-scale centralized production of electricity from fossil fuels at large thermal power plants, nuclear power plants, and hydroelectric power plants with further transmission of electricity through extensive networks to large industrial and small household consumers. But the global trend reveals a paradoxical situation – small-scale production at the local level (close proximity to the consumer) can provide economically profitable and technologically perfect, less resource-consuming conditions for the operation of the power system compared to a traditionally consolidated one. In the nearest future, the widespread use of systems with distributed generation will become simply necessary where the development of industry takes place in large areas (for example, the steppe regions of Ukraine) or a difficult-to-access places (the mountainous regions of the Carpathians), at a low population density, or for industrial facilities where it is unprofitable to transport electricity. Therefore, existing coal mines with developed infrastructure are attractive objects for the creation of small thermal energy complexes on their territory, where all the necessary conditions are present: there is a large land allotment; surface technological complex with
