Features of Modeling Aerogasodynamics of Coal Mine Face

Abstract

analysis of major accidents at the Severnaya (2016) and listvyazhnaya (2021) coal mines revealed a number of problems related to ventilation. the aerologi cal safety of a coal mine is achieved by the correct choice of technological solutions in the design, and in the process of coal mining -by operational control of the state of the mine atmosphere and gas emission control. Cur rently, coal mines, due to the high gas content, use a whole range of measures, including new ventilation schemes, various types of degassing and gas suc tion. at the same time, design and regulatory documents do not offer solu tions for calculations in a single system of all thrust sources. as the conducted studies have shown, three-dimensional modelling allows us to evaluate the mutual influence of all methods of gas emission control in a single system.
