FIELD: mining.
SUBSTANCE: installation includes fan, delivery line, inducing and water-spraying device installed on its end. Inducing and water-spraying device includes outlet head with annular outlet slot, receiver and compressed air supply nozzle. In order to increase energy use efficiency of compressed air owing to active mixing of inducing and induced jets, separation effect of inducing jet from convex surface is used in inducing and water-spraying device. Common air jet is passed through two-layer fine-meshed screen before it is emitted to atmosphere of mine working. In order to protect outlet slot against deformations, at HWL (high-water level) impact, inducing and water-spraying device is equipped with deformation-proof flange. Water supply nozzles to inner cavity of the main diffuser are installed on convex surface of the main diffuser at angles of 120 degrees to each other.
EFFECT: higher use efficiency of compressed air energy.
