Abstract

The paper presents the results of mathematical modeling of the propagation of air shock waves during a methane explosion in mine entries, considering their interaction with prefabricated parachute stoppings. Parachute stoppings can reduce the intensity of the shock wave when the intensity of the incident shock wave does not exceed the critical value of the stopping tearing off. The gas-dynamic method for calculating explosion-proof distances makes it possible to consider the parachute stoppings installed in different places of the mine entries and calculate the parameters of shock waves that have passed through the stopping.
