“…The development and implementation of resource-saving technological processes, which save not only living, but also materialized labor, is an important factor in the development of production at this stage [36][37][38][39]. At the same time, a very important condition is the reduction of total expenses and social production expenses, which are reflected in an integrated form in the cost price of final products [40,41].…”

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.

The purpose of this work was to investigate the effect of the burning environment on the properties and phase composition of clinker-based ceramic specimens made from loam with diatomite and bentonite clay in order to develop technological parameters for the manufacture of clinker products. The main raw material used for the experiments was local fusible loam from the Almaty deposit, which is the basis for the production of 75 and 100 grade ceramic bricks. Diatomite from Utesai deposit (Aktobe region) and highly plastic bentonite clay from Darbazin deposit (Turkestan region) were used as additives. Loam and bentonite clay were applied after grinding and sieving through a 1 mm sieve. Diatomite was applied after grinding and milling until it had completely passed through a 0.315 mm sieve. The raw materials are mixed after dosing, and then water is added in the amount required until a pliable mass is obtained. To investigate the properties of the products, standard cylinder samples were prepared with a diameter of 50 mm and a height of 50 mm. The cylinder samples were pressed on a hydraulic press at a pressure of 2–4 kN. The samples were dried in a desiccator at 95–100 °C for 2 h. After drying, the products were burning in a muffle kiln. The analysis of the properties of the burned products showed that the optimum ratio in the ceramic mixture of loam and diatomite to loam and bentonite clay is 85%:15%. After burning in a slightly oxidising environment at 1170 °C, the ceramic specimens correspond to Class 2 for the medium-density and compressive strength grades M 400 and M 500 (GOST 530-2012 (Government standard). X-ray diffractometric analysis showed that the products contain augite, quartz and anorthite as crystalline phases, with the former predominating. After burning in a reducing atmosphere, at 1170 °C, the properties of the samples have higher values compared to the samples burning in a weakly oxidising atmosphere. The resulting properties, according to the regulations, are characteristic of clinker bricks (DIN V 105-1 (technical requirements for clinker façade bricks). After burning in a reducing environment, the phase composition of the products changes qualitatively; in addition to augite and quartz, albite, diopside, orthoclase and haematite are present in the samples.
