COMPLEX MATHEMATICAL MODEL OF THERMODYNAMIC PROCESSES OF COAL MINES

Abstract

At present, the development of the coal industry in Russia largely depends on the efficiency of solving problems that ensure safe and comfortable working conditions. Such problems include preventing geodynamic phenomena, intensifying the degassing of coal-bearing strata, reducing air dust, improving the schemes and methods of ventilation of mine workings, forecasting and preventing mine fires, and ensuring sanitary and hygienic working conditions. The efficiency of solving these problems significantly depends on the level of knowledge of the laws of interaction between geomechanical, gas-dynamic and thermodynamic processes. The first two types of processes have been studied in sufficient detail and regulatory documents have been developed based on the research results. However, the nature of thermodynamic processes in the rock mass and their role in the occurrence of endogenous fires, the influence on the nature of the temperature distribution of ventilation flows during the development of coal seams prone and very prone to spontaneous combustion have not been fully studied. In this regard, the study of the laws of heat transfer in the mine atmosphere and coal rock mass under normal conditions and in the presence of a fire source to ensure safe and comfortable working conditions in coal mines is an urgent scientific task.
