Liao, C F; Graham, G W

A method for removing the dust from the operator' work area of a longwall shearer, said shearer having at least one rotating drum for shearing coal from the longwall coal face, said method is described comprising: producing a water mist having a particle size between 1 and 50 microns using water plus a compressed gas; directing said water mist along a confined path to induce an air flow along the path from one end toward the other end; and positioning said path so that dust-laden air is drawn from the operator's work area into said one end of the path and discharged from the other end of the path adjacent the longwall coal face.
