Water Infusion for Coal Mine Dust Control: Three Case Studies.
McClelland-JJ; Organiscak-JA; Jankowski-RA; Pothini-BR
This Bureau of Mines report discusses recent applications of water infusion technology to control dust in U.S. coal mines and presents recommended guidelines for determining coal seam infusibility. The techniques required to use water infusion are presented in detail. A Bureau case study indicated that water infusion reduced dust levels by 68 pct along a longwall plow face, bringing this section into compliance with the 2.0-Mg/m3 federal dust standard. Similar studies conducted by Occidental Research Corp. under a Bureau contract show that water infusion at two longwall double-drum shearer operations produced dust reductions ranging from 38 to 50 pct. Water infusion was found to be cost effective, averaging 5 cents per ton.
