Substantiating the operating parameters for an underground gas generator as a basic segment of the mining energy-chemical complex

Abstract This paper presents the main aspects of changing the coal mining technology based on the introduction of underground coal gasification technology for the mining-geological conditions of the occurrence of State Enterprise “Lvivvuhillia” coal seams on the example of “Chervonohradska” mine. When conducting analytical studies using the “Material-heat balance of underground coal gasification” software, predictive quantitative-qualitative indicators of the injected blast mixture and gasification products have been determined depending on the structure and elemental composition of the coal seam, host rocks, water saturation of the seam, and water inflow into the gasification channel. The heat energy loss of an underground gas generator during the gasification of thin and ultra-thin coal seams has been revealed. The heat and energy capacity of the underground gas generator has been determined depending on the type of supply of the injected blast mixture to the combustion face “mirror” and the performance indicators of the gas generator segment within the mining energy-chemical complex taking into account the quantitative-qualitative indicators of generator gas and liquid chemical raw material of the condensate.
