Analysis of emergency operation modes of a tunnel ventilation systems used in subway systems has shown that they do not provide stable gas air streams in case of fire in the rolling stock and its stop in the tunnel, and there is no methodological support for calculations of stability of gas air streams in tunnel fires. The existing technology of assessing the stability of ventilation streams applied in coal mines and road tunnels did not take into account the characteristics of fires in subways.
