FIELD: mining.
SUBSTANCE: automated system for air-and-gas control and prevention of explosion in a working face with a sprinkling device of a mine working and with a winning machine includes stationary temperature sensors installed on each section of the support and at least one complex measuring device installed on the winning machine and provided with a methane sensor, a temperature sensor and a carbon oxide sensor, which are compactly arranged in a single housing. A sequence of each monitoring and control unit includes logic of comparison of measurements of the temperature sensor installed on the winning machine to measurements of stationary temperature sensors for output of a warning signal at fixation of insufficient coincidence of the above measurements. Besides, monitoring and control units are provided with radio modules for wireless communication to the complex measuring device and the stationary temperature sensors. The complex measuring device can include a carbon oxide sensor, and the monitoring and control units have a possibility of activation of operation of the sprinkling device. On the winning machine there can be arranged two complex measuring devices on maximum remote ends of its housing.
EFFECT: minimising explosion hazard by reliable detection of manipulation with gas sensors and prevention of coal self-ignition in a working face.
