Dust Control in Longwall Shearer Faces Through Air Movement by Water Sprays.
Longwall-shortwall Mining State-of-the-art SME/AIME New York, New York, 1981 :115-120
This paper describes a Bureau of Mines research project that resulted in a simple procedure for reducing the dust exposure of longwall shearer operators. The project involved researching and testing a water spray and passive shield system to hold dust against the face and away from the shearer operators. The system is known as the shearer-clearer.
