FIELD: mining operations.
SUBSTANCE: invention relates to mining, namely to the field of prevention of ignition and explosion methane-air mixtures, and can be used in coal mining by underground method. The method of prevention of ignition of methane-air mixture is proposed, comprising pneumatic hydro-irrigation of the area of mining operations, the automatic monitoring of methane content by the sensors, and placement of the inhibitor to the mining atmosphere. The difference is that when the concentration of methane in the air is reached to 2.5% the supply of air into the system is automatically disconnected with simultaneous connecting under pressure of the inhibitor of given concentration, the water supply to the pneumatic hydro-irrigation system is not disconnected at that.
EFFECT: neutralising the occurred methane-air mixtures and location in the initial stage of their occurrence.
