A feasibility study on the use of foam to reduce respirable dust on a Joy 10Cm continuous miner.
NTIS: PB 241 176, 1974; :1-29
In operations in the Illinois No. 6 Coal seam, the effectiveness of foam was compared with that of water in reducing respirable coal dust. A combination of 39 foam generators and 14 water sprays were used during the foam tests. Sixty-one water sprays were operated during the water tests. Results of 45 shifts of dust sampling (24 with foam and 21 with water) show no significant difference in dust levels at the miner operator, shuttle car operator, and belt transfer point when either foam or water was used.
