Abstract
The results of inventive work at the Institute of Geology and Geochemistry of Combustible Minerals of the National Academy of Sciences of Ukraine in 2024 were considered:
– the method of obtaining thermal energy from mine workings includes pumping mine water and ventilation air to the day surface, extracting low-potential thermal energy using heat pumps, and supplying heated water to consumers;
– the method of thermal coal processing includes continuous sectional loading of coal, gradual heating, regulation of the speed of section movement, temperature control of the process, and production of gas, liquid, and solid products;
– the three-section unit for heat recovery from mine workings includes supply and storage pipelines for mine water and ventilation air, appropriate heat exchangers, heat pumps, and a heated water storage tank with a discharge pipeline;
– the energy complex for the processing of carbon-containing raw materials includes a raw material gasifier that produces a mixture of combustible gases, carbon dioxide CO2 and warm water as gasification products.; The complex additionally includes a bioreactor, which, after gasification, receives carbon dioxide and a portion of the waste heat water, which intensify the growth of algae in the bioreactor for processing in a separate module into as biofuel;
– the method of underground gasification of coal for synthesis gas and methane production were implemented at temperatures from 950 to 1 150 °C and a pressure of 0.5 to 1.0 MPa. We produce methane-containing coal gas from the coalcontaining thickness above the gasification layer;
– the method of combined conversion of non-conditional coal includes the production of synthesis gas of CO + H2 at gasification of a water coal pulp in a ratio of 1:1 in a coil reactor, simultaneous pyrolysis of lump coal in the reactor, exhaust of CO, H2, CH4, CO2 with the production of resin products;
– the method of predicting enriched horizons of metal-bearing deposits includes geological and structural processing and interpretation of the study area, allocation of promising areas in the search for elements, calculation of their density, construction of maps, diagrams, schemes and determination of the structure of objects, analysis of the relief and establishment of block and ring structures, which are used to predict promising objects in terms of mineral deposits in the study area.
