Development of a Waterjet Assisted Coal Plow (The Hydrominer)
High pressure water jets were assessed for their possible application to coal cutting on longwall faces. The Hydrominer machine has high pressure water jets on the leading edge of a plough shaped machine which cuts and loads the coal from the face. This machine can help to eliminate the disadvantages of conventional mining such as the slowing down of the machine to maintain constant instantaneous output, the production of large quantities of small coal, the creation of large volumes of respirable dust and the high velocity of travel of the pick across the face which can lead to methane ignition. Paper presented at Industry Meeting on Water-Jet Assisted Cutting, held in Pittsburgh, U.S.A. on June 21, 1984. (H.C.B.)
