Abstract
The Bureau of Mines has introduced several techniques for enhanced dust control at longwall faces. The purpose is to minimize dust concentrations in the face area by suppressing the dust produced by the stage loader and shearer. Stage loader dust control is achieved by the installation of dust collectors and water sprays at the crusher. Bureau research has shown significant dust reductions through the use of new types of compact, high effective dust scrubbers. Shearer generated dust is the largest single dust source at the longwall face. Through the use of inward facing high pressure drum sprays and remote control the shearer operators are kept away from the dust cloud and in the intake air. In addition to the above, this paper discusses the use of foam and reverse drum rotation in dealing with longwall dust.
