Abstract
This work is devoted to identifying and describing the features of the integrated utilization of self-heating coal-mine waste dumps. The research employed methods of scientific analysis and generalization, as well as scenario-based design. Self-heating coal-mine waste dumps are presented as multifunctional technogenic geo-resources charac-terized by the trinity of energy, material, and spatial resources. Distinctive features of such dumps have been identified, the main ones being their thermal state, lithological and mineralogical composition, and the location of the dumps rela-tive to geodynamically active zones. It is demonastrated that during the exploitation of the energy resource, a self-heating coal-mine waste dump can be used both as a heat generator and a heat accumulator, while in the processes of exploiting material or spatial resources, it can serve respectively as a source of oxidized rocks and as an accumulative landform element. As a geotechnological feature of the integrated utilization of self-heating coal-mine waste dumps, the priority exploitation of their energy resources has been identified, including the utilization of non-renewable heat gener-ated by the dumps and renewable heat accumulated by the near-surface rocks due to solar radiation absorption. As a biotechnological feature of the integrated utilization of self-heating waste masses, the creation of favorable conditions for the long-term heat-generating activity of the waste dump microbial population has been highlighted, which corre-sponds to the principles of bioethics. The identified features should be taken into account during the development and implementation of scenarios for the integrated utilization of self-heating coal-mine waste dumps in the Donbas.
