Modeling of Operation of a Solid-Propellant Pulse Aerosol Generator during Extinguishing of Methane—Air Mixture Ignition in Coal Mine Drifts

摘要

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.
