Increased levels of coal production on longwalls has brought with it higher levels of dust generation. Most United States longwalls have diffuculty complying with federal dust standards which are much stricter than those imposed in Europe. This program offers the mining industry the opportunity to sort out and share assessments of the dust control techniques in use today and those proposed for the future. This objective is being achieved through laboratory and field evaluations of both available and proposed dust control practices using innovative sampling procedures and state-of-the-art respirable dust monitors and instrumentation. In this manner, the effectiveness or lack of effectiveness of longwall dust control techniques can be quantified, thereby providing the information necessary for proper application of these techniques. This program is investigating nine different dust control techniques. This report documents the Phase II effort on each of the subprograms: Passive Barriers/Spray Air Movers for Dust Control at the Shearer; Practical Aspects of Deep Cutting; Stage Loader Dust Control; Longwall Automation Technology (remote control); Longwall Application of Ventilation Curtains; Reversed Drum Rotation; Reduction of Shield Generated Dust; Air Canopies for Longwalls; and Mining Practices. Each of these dust control methods was investigated, usually at a few or several mines, and the results were often supplemented by discussion with manufacturers and special sampling tests.
