Alab'yev V. Perfection of methods and facilities of normalization of the thermal mode of deep coal mines

The object of study - the processes of heat and mass transfer in the mines under natural conditions of formation of the thermal regime and the presence of pipes with heat and cooling SKRP, which affect the formation of the thermal regime of the coal mines. The aim is to establish patterns of heat-mass transfer in deadlock workings in the system "environment - pipeline - gas decontamination" to improve methods of forecasting temperature when determining coolconsumption workings of different functions, and study new ways and means of regulating the thermal regime of the coal mines, which provide safe the use of SKRP and gas heat generators, using secondary sources of energy. Research methods: analysis of scientific, technical and legal literature on the safe use of air conditioning and heating the air of mining air supply shaft coal mines; analysis of the conditions of occurrence of potential hazards associated with the use of refrigeration in a coal mine methane utilization in coal-fired plants; Experimental study of conditions of formation of a thermal mode of coal mines; testing and introduction of new models in the mines of mine refrigeration, ways and means of heating air supply shaft; theoretical studies, based on the theory of similarity, mountain thermal physics, classical thermogasdynamics; comparative analysis of the results of theoretical and experimental research data. The mathematical models of heat and mass transfer of air in the dead-end development workings in the discharge circuit airing, both in vivo formation of the thermal regime, and artificial cooling of air. Adjusted method of forecasting the temperature conditions in the mines, which airs local ventilation fans. Based on the assumption of a linear temperature change in the coolant pipes of mine adjusted depending on the definition of the calculated temperature in the mines, which are aired by whole mine depression. The use of stationary refrigeration equipment 1 MW of cold in the 3rd East and West 4th lavas seam mines m3 "Scheglovska- Glubokaya " SJSC "Shakhtoupravleniye" Donbass "" allowed almost completely normalize the thermal conditions in these faces. The annual economic effect of the introduction of refrigeration equipment at the mine amounted to 2073.1 thousand. UAH in the first year of its operation.
