ABSTRACT:
A method and apparatus for controlling the dust produced by continuous underground coal mining machinery. The apparatus comprises a wet scrubber mounted on the pivoted boom adjacent the cutting head and discharges the cleaned air into the air curtain flow. The wet scrubber utilizes twin fluid atomizers to reduce the quantity of water required, produce fine water mist, and permit discharge of the dust-laden air directly to the mine.
