MOBILE DEVICE FOR INHIBITION OF HIGHLY EXPLOSIVE METHANE-AIR MIXTURES IN MINES (VERSIONS) Russian patent published in 2014 - IPC E21F5/04 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry and can be used to prevent ignition and explosion of methane-air mixture. The mobile device to inhibit highly explosive methane-air mixture is proposed in two embodiments: mobile on trolley with unit of spray nozzles and knapsack embodiment for immediate protection of workers in the mine. The mobile device for inhibiting highly explosive methane-air mixture in the mines of the first embodiment comprises cylinders with inhibitor, methane sensor, an electronic pressure gauge, a power supply, a trolley on wheels. The device additionally comprises a control unit connected to the system of control and monitoring of the mine and receiving a signal from the sensors of methane and pressure gauges, and transmitting signal to the control valves, which are connected simultaneously with the control unit and cylinders with inhibitor. The control unit is connected to the unit of nozzles comprising two mutually isolated chambers for supplying the inhibitor. In the second embodiment, the mobile device to inhibit highly explosive methane-air mixture in the mines comprises cylinders, methane sensor, and pressure gauges. The device additionally comprises a control unit connected to the cylinders with inhibitor and simultaneously through the flexible connection to the control valve, with at least one spray nozzle to the rod. The control unit and the control valve consist of two isolated chambers for supplying inhibitor, and the control valve is provided with a switching key.

EFFECT: neutralisation of highly explosive concentrations of methane and providing safety and absolute protection of miners due to the rapid and mobile delivery and application of inhibition of methane.
