This paper presents a study to evaluate the water-jet-assisted (WJA) mechanical cutting of oil shale under actual mining conditions. 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. The successful application of high-pressure water-jet technology in conjunction with mechanical mining could favorably impact the mining of oil shale by reducing capital and operating costs, improving safety, and increasing the extraction ratio of oil shale mined. The WJA roadheader field tests on coal have shown that high-pressure water-jets increase cutter life and reduce ventilation costs by cooling the cutting head, removing already mined rock from the cutting surface, and reducing dust production.
