FIELD: mining industry. SUBSTANCE: this can be used in gaseous fiery mines and at other objects where explosion-risk gases or their mixes can appear. Head lamp with explosive mixture alarm has lamp with bulb, combustion chamber, and power source. Filament of bulb is in series connected in power source circuit. Combustion chamber is provided with gas igniter, flame stabilizer, and peephole. When lower limit of gas explosibility appears in combustion chamber, gas flashing or explosion takes place due to igniter within limits combustion chamber inner space. EFFECT: high efficiency. 4 cl, 2 dwg
