Zusammenfassung:	FIELD: methods of hydraulic mining, particularly hydraulic monitors for rock breakage with water jets. ^ SUBSTANCE: hydraulic monitor comprises base, hinge assembly and barrel with nozzle. Through pipe extending along barrel axis is installed in barrel channel and supported by centrators. The first pipe end is communicated with atmosphere, another one is located in the nozzle. Pipe-nozzle diameter ratio is 0.50-0.57. The pipe serves as ejection means. As high pressure water passes through the nozzle streamlined air bubble is created at pipe outlet due to air ejection. Air bubble pressure is less than atmospheric pressure. This provides jet compression at nozzle outlet and as a result increases jet range. Abrasive and chemical materials may be used with water jet to improve rock breakage efficiency. ^ EFFECT: increased efficiency. ^ 1 dwg
