FIELD: mining, particularly for mine venting.
SUBSTANCE: device comprises receiver made as torus-shaped chamber with annular slot, receiving pipe, perforated diffuser and compressed air and water supply nipples. Device also has aerodynamic lattice installed at exit receiving pipe section and adapted to split both jets into separate ones to create efflux jet having semi-uniform velocity profile, maximal pressure head and increased jet range at mixing chamber outlet.
EFFECT: decreased device size and increased economical efficiency of device operation.
