Abstract A cowl-like scrubber (20) for removing dust generated by a longwall shearer has a housing (21) adapted to be mounted on the shearer near a cutter drum. An air inlet (23) is provided in the housing to allow the dust- laden air to enter the scrubber (20). Downstream from the inlet area is an arrangement of jet spray nozzles (30) which impart high velocity, small diameter water droplets. The water droplets entrain the dust particles in the dust-laden air and move the resulting dust-laden mist to a mist eliminator (40) downstream from the jet spray nozzles where the dust-laden mist is then removed from the air.
