Numerical study of the effectiveness of explosion-proof water barriers in case of an emergency methane explosion in coal mines

The results of numerical simulation of the damping of an air shock wave from an emergency methane explosion in a mine are presented. The results of an analysis of the effectiveness of using water barriers to reduce the intensity of air shock wave, depending on their length, are presented. The effect of the gradual deposition of water droplets from the water barrier onto the walls of the mine on the intensity of the shock wave passing through the barrier has been determined. The rate of precipitation of water droplets from the gas-droplet mixture formed by the interaction of the shock wave with the water barrier has little effect on the intensity of the shock wave passing through the barrier.
