FIELD: technological processes.
SUBSTANCE: invention relates to technical means of destruction of materials by liquid jet and can be used, in particular, in mining industry for hydraulic destruction of rock massifs during development of mineral deposits. Hydraulic monitor comprises a barrel with a nozzle hydraulically connected to the supply line, an ejecting device located outside the area of the hydraulic monitor shaft and provided with a mixing chamber for feeding solid particles from the accumulator into the area of the hydraulic monitor shaft, note here that supply line is equipped with gate valve to control water pressure in hydraulic monitor shaft.
EFFECT: increased destructive power of hydraulic monitor jet and productivity of jetting.
