FIELD: mining.
SUBSTANCE: system includes device for automatic registration of mine atmosphere components condition indices - methane-air mixtures and/or coal dust. Device is composed of the following components: methane, carbon oxide, hydrogen, oxygen, dust and temperature. Sensors that register practically all explosive parametres automatically transmit measured values of parametres into computer that controls operation of screen.
EFFECT: improved reliability and efficiency of fire and explosion protection of mines by arrangement of screen on the way of explosions and flame propagation before combustion products are generated.
