It is theoretically established that in order to ensure the best heat transfer from the depth of the array to the well collector, it is necessary to minimize the negative impact of technogenic rock fractures near the surface of the pipes of the geothermal heat exchanger. For this purpose, it is advisable to fill these voids with a solid composition based on an inexpensive substance, such as clay, with the addition of a thermally conductive filler, as it is advisable to use graphite powder. mixtures. The use of clay-graphite mixture as filler annulus with a mass fraction of graphite 50% will increase the specific removal of heat, and therefore reduce the length of the well by 1.7 times. The implementation of the study allowed us to determine the conditions for heat transfer in the system "rock mass - geothermal heat exchanger - aquatic environment" in the bio-treatment facility on the basis of which the parameters of technology for restoration of biological diversity in the produced quarry space using geothermal energy were calculated. The technology of restoration of biological diversity in the produced open spaces of the quarries with the use of geothermal energy has been developed, which includes formation of the bottom of the quarry with a slope, for the organization of movement of water flow by gravity, construction of the main and auxiliary dams, in order to increase the duration of passage of water through the quarry. drilling, well drilling and construction of coaxial heat exchangers, for creation of geothermal system of heat collecting, positioning of quarry boards, construction of reservoir at the bottom of the quarry, for additional och forgiveness and collecting water planting surface water dams and higher aquatic plants (reed, cattail, pit water for cleaning.
