Abstract: This invention relates to a method for hydraulically mining of coal. An entry is driven upwardly through a panel of coal to a predetermined terminus and a fluming system, which slopes in the same direction as the entry, is installed in the entry. A monitor is positioned in the entry and a high pressure jet of water from the monitor is employed to cut coal from the face area of the panel of coal. The cut and broken coal is then further broken with a jet of high pressure water from a second monitor positioned in the entry and located near the face area. The broken coal then is fed to the fluming system and transported through the flume with the aid of gravity as a coal-water slurry.
