The results of mathematical modeling of the formation of the field of gas concentrations in the vicinity of the mine fire source are presented. A mathematical model is proposed for the unsteady transfer of any gas in mine workings during fires, which allows one to study all the regularities of filling isolated and semi-isolated volumes of any gas at a constant or variable rate of their formation in time. The promising directions of further scientific work in the field of non-stationary distribution of fire gases along the length and cross-section of mine workings in case of accidents are presented, which include a number of theoretical and experimental studies
