Abstract

1449886 Ventilating mines COAL INDUSTRY (PATENTS) Ltd 1 March 1974 [16 March 1973] 12738/73 Heading F4V [Also in Divisions E1-E2] In a mine roof support assembly comprising at least one hydraulic prop 10 supporting a roof canopy 11, apparatus 20 for inducing an air flow is arranged along the said canopy for directing fines into the goaf. The apparatus 20 is in the form of a tube, open at one end 23 and with a hinged flap at the other end. A fluid outlet nozzle is disposed on a radial arm adjacent the open end 23 and a jet of water issuing therefrom induces a flow of air through the tube which is provided with a wedge-shaped inlet slot 27. For numerous minor details concerning number and disposition of nozzles, shapes of tube and slots &c. the Specification should be referred to.
