NTIS: PB/241-882 :83 pages
A design study investigated the feasibility of using high-pressure water-jet cutting in the continuous mining of coal in underground mines. The potential advantages of this approach include the reduction of dust and sparking hazards and the minimization of damage to overlying rock strata thus reducing the roof fall hazard. Based on a study of the predicted coal cutting characteristics of the high-pressure jet cutter continuous miner, it was concluded that achievement of a competitive production rate would require more power than is practical to install on an underground machine.
