摘要：
The study of aerogasdynamics of long tunnels during the period of their construction is an urgent scientific and technical problem. On the basis of experimental and theoretical studies, the existing regularities of gas exchange of the rock mass with the atmosphere of the tunnels and the regularities of the air-gas-dynamic processes of the transfer of gas impurities to the atmosphere of tunnels of large cross-section were clarified, which made it possible to improve the methodology for calculating the amount of air and predicting gas situations for underground tunnels under construction.
