Abstract
This report represents the results of in-mine demonstration of three dust control techniques for controlling respirable dust levels on shearer-longwall faces. The techniques were water infusion, foam spray, and reverse shearer drum rotation. The mines in which tests were conducted were in the Upper Freeport seam and Pocahontas No. 3 Seam. Both gravimetric samples and gca ram-1 real time dust monitors were used for dust surveys. Dust control technology was reviewed, pertinent techniques were selected, and equipment was procured and demonstrated as part of the program. The results indicated that water infusion can be readily implemented; foam spray holds promise, but requires more work to be done; and reverse drum rotation is effective in select conditions.
