Abstract

In the general case, substandard combustible minerals include on-balance and off-balance reserves of primary energy materials – coal and peat deposits (solid combustible minerals) and oil and natural gas deposits (liquid and gaseous combustible minerals), which by physico-chemical, energy or geological-spatial conditions do not meet the economic criteria for extraction and use of traditional technological methods, as well as the potential of methane from coal deposits, arrays of man-made carbon-containing materials such as waste from coal mining, coal beneficiation, refining, etc. Review of the available reserves in terms of the use of modern technologies of environmentally friendly conversion can significantly expand the opportunities for the development of all types of combustible minerals in Ukraine.

The paper considers the geological zoning of oil and gas fields and deposits of solid combustible minerals, as well as their reserves and production. It is shown that the reserves of the main primary energy resources in Ukraine many times exceeds the extraction and has significant opportunities to increase due to the use of substandard combustible minerals.

The principles of ecologically safe conversion of substandard combustible minerals in terrestrial and underground conditions are presented. The importance of energy utilization of methane from coal deposits, arrays of such man-made carbon-containing materials as coal mining waste, coal beneficiation, oil refining, etc. was noted. The main mining-geological and technological criteria that contribute to the development of coal seams by underground gasification are given, as well as deposits and areas of coal basins of Ukraine that are suitable for underground gasification.

Abstract

An analysis of Ukraine’s sustainable development targets, in particular in the field of energy, resource management and environmental protection, are presented. It is shown that regional energetic is a determining factor for achieving the aims of sustainable development.

Changes in the natural environment in Ukraine due to external (global) and internal (local) factors that are intertwined and overlapped can cause threats to socio-economic development. It is proved that in the areas of mining and industrial activity a multiple increase in emissions of pollutants into the environment are observed.

The comparison confirmed the overall compliance of the structure of consumption of primary energy resources (solid fossil fuels, natural gas, nuclear fuel, oil and petroleum products, renewable energy sources) in Ukraine and in the European Union, shows a steaby trend to reduce the share of solid fuels and natural gas and increasing the shares of energy from renewable sources.

For example, in Ukraine the shares in the production and cost of electricity in 2018 was: the nuclear power plants – 54.33 % and in the cost – 26.60 %, the thermal power – 35.95 and 59.52 %, the renewable energy sources – 9.6 and 13.88 %.

The energy component must be given priority, as it is crucial for achieving of all other goals of sustainable development and harmonization of socio-economic progress.

The paper systematizes the indicators of regional energy efficiency and proposes a dynamic model for the transition to sustainable energy development of the region.
