Abstract
This report includes a review of all relevant data on underground hydraulic coal mining technology collected during the contract, as well as data on U.S. coal seam conditions, analysis of the applicablity of various hydraulic technology in U.S. coal mines, economic comparison, and recommendations for further research. It concludes that hydraulic mining using a monitor with roof caving and fluming of the coal has high potential for use in pitching, multiple seam coal deposits in areas of Colorado, Wyoming, and Washington. The system has advantages with respect to health and safety, productivity, and recovery of resources. Productivity can reach 20 to 30 tons of raw coal per man shift at mining costs of $5 to $10 per ton of raw coal, based on 1975 prices.
