Proc 2nd Int Conf Innovative Min Sys University Park, Pennsylvania, 10/27-29/86 :56-68
This paper describes the basics of water-jet-assisted cutting, design features of the shearer and the testing of its components such as high pressure water pumps, phased rotary water seals, bit- force-actuated water valves, and jet nozzles. Also, the water- jetting system and its layout in the longwall installation and the underground cutting trial is discussed in detail.
