Abstract
Tests indicate that the combination of water jets and polycrystalline diamond composite cutting tools may represent the first major advance in hardrock cutting technology since the introduction of tungsten carbide tools about 40 years ago. The tests were conducted on a sample of oil shale with a uniaxial compressive strength of 85.5 to 109.7 Mpa, using a roadheader machine. The tests were conducted in the fall of 1989 by the U.S. Department of Energy at the facilities of Alpine Equipment at State College, Pennsylvania. Technical and financial support was provided by the Colorado Mining Association and the U.S. Bureau of Mines.
