Abstract
The physical characteristics of oil shale (a dolomitic limestone containing kerogen) make conventional mechanized production mining methods impractical by causing excessive machine vibration, high bit- wear rates, and excessive dust generation. Current mechanical excavation methods for oil shale are less efficient and more costly than the traditional drill-and-blast methods, but conventional drill- and-blast methods have limitations imposed by excessive rock damage and regulatory considerations. By improving mechanical excavation technologies, oil shale could be more competitive with other energy sources. The U.S. Department of Energy's Grand Junction Project Office is participating in a $1.5 million cooperative agreement with Alpine Equipment Corp./Astro International Corp. (Alpine) of State College, Pennsylvania, to evaluate the water-jet-assisted (WJA) mechanical cutting of oil shale under actual mining conditions. This evaluation of high-pressure water-jet technology in conjunction with mechanical mining under actual mining conditions will provide data that can be utilized by the private sector to develop and commercialize WJA mechanized mining equipment to mine oil shale.
