Abstract
Operation of a pulse aerosol system of extinguishing fires caused by ignition of a methane–air mixture in drifts and coalfaces of coal mines is modeled. A computational experiment shows that such a system can cut off the shock wave propagating over the coal mine drift filled by a combustible methane–air mixture, suppress burning, and protect people and equipment in the mine from the shock wave action.
