Abstract
This report presents preliminary design and systems specifications of a demonstration miner (hydrominer), mining configurations showing good promise for typical U.S. thick coal seams in three seam pitch categories, and a definition of a test program that will provide sufficient engineering data for the design of a water jet cutting head adequate to cut coal in U.S. thick coal seams. The cost analysis data showed hydraulic methods to be economically competitive with present thick seam mining methods. It was also obvious from studies of thick seam methods that the hydrominer coal breaking techniques are more effective in removing most of the coal with its long reach of 60 feet or more; it is a safer mining system, and it produces very low coal dust content in the air.
