In the reservoir 7 form a container 8 for the underwater storage of enriched soil 5. With a capacity of 8 divided by a dam 9 to prevent dilution of enriched soil 5 clayey soils 6 and on the lower end of the vessel 8 in advance put the head part 10 suction head; it 11. Further enriched soil 5 zamyvayut head part 10 suction head; it 11 and form the warehouse 12 and clarified GidroMash containing clayey soils, dropping the blade 15. The development of soil from warehouse 12, his ascent to the surface and hydrotestosterone in the form of a pulp to the place of laying produce by filing in the head part 10 suction head; it is 11 high-pressure water. Water is supplied by a pump 13 through a flexible water pipe 14 which is connected to the head part 10. Formed in the head part 10 the pulp is then fed through a flexible pipeline 16 to the surface and then through the main pipeline 17 to the map of reclamation 18. On the extended season excavation of the warehouse is carried out under ice 19. In the way as the head part 10 suction head; it 11 can be used in different types of jet pumps: hydraulic Elevator, whirlpool jet pumps, injectors, etc.

FIELD: mining industry, particularly to produce loose, soft or single-grained minerals through production boreholes.

SUBSTANCE: method involves installing drilling rig in one point of area to be treated; drilling inclined production boreholes at an angle to horizon; installing pipes in the borehole; assembling hydraulic production equipment and lifting mineral to surface. Drilling rig is installed in one point to be treated so that the drilling rig may perform azimuth and angular rotation in vertical plane. Several production boreholes extending at different angles to horizon in common vertical plane are drilled by the drilling rig. The first borehole has minimal angle defined by maximal possible length of borehole, which can be drilled by the drilling rig. The next borehole has maximal angle defined by rock deformation area to prevent rock deformation on surface and in mineral production equipment installation area. Remainder boreholes are drilled in the same vertical plane at α3, α4, ... απ angles to horizon, which maximizes efficiency of mineral production. Similar inclined boreholes are drilled in other vertical planes by rotating the drilling rig in azimuth direction through γ1, γ2 ... γπ angles. Mineral is produced simultaneously or sequentially from borehole groups to provide smooth lowering of overlaying rock.

EFFECT: increased mineral removing fullness with the use of single equipment unit, reduced amount of construction-and-assembling operations, possibility to perform operations in any season, reduced costs of operation performing in cold season, increased safety for staff and equipment.

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.
