Study on gas diffusion evolution and emergency evacuation in tunnel with sudden wind shutdown

In order to solve the problem that a large amount of gas emitted from the newly excavated coal wall in the driving roadway after the sudden wind shutdown causes the gas volume fraction to rise rapidly and thus endangers the safety of the operators, this paper proposes a mathematical model for the sp...
