Abstract

1433193 Mining conveyers GEWERKSCHAFT EISENHUTTE WESTFALIA 27 April 1973 [29 April 1972 16 Nov 1972] 20130/73 Heading B8A [Also in Divisions E1-E2 and F2] In a mineral mining installation a long wall conveyer 10 consisting of a series of interconnected line pans is provided with a goaf side guide bar 11 for a winning machine and an upwardly directed bar 12 for supporting the components of a water spray dust supression system. A water supply 2 feeds control units 1 which have feelers 15 projecting into the path of the machine and which feed spray heads 3 directed over the conveyer. Deflection of the feelers in either direction initiates spraying and the sprays remain on until a damped spring mechanism returns the feelers. The feelers can contain spray nozzles.
