The article presents results of the numerical studies of aerodynamic processes in excavated sections of coal mines. The effect of the ventilation and degassing schemes and their parameters on the oxygen content and a danger of spontaneous coal combustion are described. The influence of geological and mining factors on the endogenous fire hazard of the coal bed prone to spontaneous combustion is analyzed. It is recommended to reduce endogenous fire hazards of mining flat gas-bearing coal beds ofdoi:10.1088/1755-1315/378/1/012020 fatcat:mxxorgkoknaubfe3ryfy33734i
