The method using the multi-function system for continuous collection of minerals submarine deposits is as follows.

Pre-set condition of the ratio of the actual current value of the working pressure in the secondary water flow (pD.P.) transporting the washed rock mass fragmentation, to the actual current value of the working pressure in the main water flow (pop), in the area of introduction in its composition podavlennoi rock mass:

Before starting a multifunctional system for continuous collection of minerals submarine deposits controlled valves 10 and 24 are fully closed.

The control unit 31 starts the pump 3 and Electromechanical actuators 6, 23, 17 and 15, 16 crushers 7, the conveyor 22, a sectional grate vibrating balanced pick-up 18 and hollow screw drivers 12, 13, respectively, and fully and partially opens managed valves 24 and 10 respectively. Consequently, the hollow screw propellers 12 and 13 provide a multifunctional system for collecting minerals underwater deposits of naturally formed on the bottom layer of rock mass 32. Pump 3 creates the main stream of water that moves through magnetite gnome pipeline 5, through a fully managed open the valve 24 directly in Flex 8. From the main flow of water injection pipe 5 is formed, the additional flow of water, which flows through the pipe 11, through the partially open controlled valve 10, the tip 25, the hopper 2, the crusher 7, additional nozzle 21 again in the main stream discharge pipe 5 and are further transported in its composition. The launch of Electromechanical actuators 17, 23 and 6 provides a sectional grate vibrating balanced pick-up 18, the conveyor 22 and crusher 7. When the control unit 31 on the basis of obtained from the integrated navigation and steering systems 9 information controls the movement of a multifunctional system for continuous collection of minerals submarine deposits, by regulation by means of Electromechanical actuators 15 and 16, the rotation speeds of the respective hollow screw propellers 12 and 13. This hollow screw propellers 12 and 13 also function as buoyancy tanks that prevent you from achieving a critical level of subsidence multifunctional system for continuous collection of minerals underwater deposits in the muddy sediments of the bottom of the reservoir, which is developing the underwater field.

After the beginning of the and movement multifunction system for continuous collection of minerals submarine deposits, the control unit 31 by means of an Electromechanical actuator 17 buries sectional grate vibrating balanced pick 18 in the layer of rock mass 32. Thus, the generated components of minerals underwater deposits of the elements in the composition of the rock mass on sectional grate vibrating balanced pick-up 18 begin to move into hopper 2.

In tank 2 receives an additional flow of water, resulting in the absolute pressure in the hopper 2 is greater than the absolute pressure in the surrounding hopper 2 environment, which causes the output of the additional flow of water through located in the bottom part of the hopper 2 reception slot 14, in the pool of the reservoir. The share generated by components of minerals underwater deposits of elements exceeds the weight of the sludge, which is part of the developed layer of rock mass 32. Thus, the output of the additional flow of water through the reception slot 14 in a pool of water, when using sectional balanced vibration pick-up 18-iron type, will ensure the effective removal of a significant amount of sludge collected from the rock mass by washing part of the additional water flow. In the hopper 2 will do the rock mass with high concentrations of whom created onetime minerals underwater deposits of elements.

After entering the hopper 2, washed the rock mass with a high concentration of the generated components of minerals underwater deposits of items transported by the conveyor 22 and the additional water flow to the crusher 7. The increase in cross-sectional area of the tip 25, in the direction of travel therein of fluid flow, increases the uniformity of transportation washed rock mass through the volume of the hopper 2. Mounted in the hopper 2, the apparatus of the direction of movement of the rock mass 29 ensures the supply of washed rock mass that is transported through the hopper 2, the boot box 19 crushers 7. In the crusher 7 is crushing the washed rock mass with subsequent transportation podavlennoi rock mass in the additional flow of water through the outlet box 20 crusher 7 and additional nozzle 21 into the main stream of water that moves in the discharge line 5. After receipt podavlennoi rock mass together with the additional flow of water into the main water flow in the discharge pipe 5 is formed, the flow of slurry, which is then transported through a flexible pipe 8 from the multi-function system for continuous collection of minerals underwater deposits. The rotary coupling 30 reduces the load on a flexible pipe 8 while maneuvering many of the functional system for continuous collection of minerals submarine deposits, which increases its service life.

With the exhaustion of the time required for the output of the pump 3 on its performance, the control unit 31 by the gauge 26 determines the actual current value of the working pressure in the secondary water flow (pD.P.)transporting the washed rock mass fragmentation, and using a pressure gauge 27 determines the actual current value of the working pressure in the main water flow (pop), in the area of introduction in its composition podavlennoi rock mass. In parallel, the control unit 31 starts to control the execution of the specified conditions and ensures the stability of its performance over time, by regulating the magnitude of costs the primary and secondary streams of water.

In case of default specified conditions, that is, RD.P.<popthe control unit 31 increases the rate of the additional water flow and reduces the rate of the main flow of water by increasing the size of the opening of the controlled valve 10 pipe 11 and reduce the size of the opening of the controlled valve 24 and the discharge pipe 5, respectively, which increases the pressure in the hopper 2.

When reaching the specified conditions, that is, RD.P.≥Ropthe control unit 31 stabilizes ve is icine opening controlled valves 10 and 24.

A constant level of penetration sectional grate vibrating balanced pick-up 18 in the layer of rock mass 32 at constant speeds of rotation of the hollow screw drivers 12, 13 ensures uniformity of receipt of the rock mass with a high concentration of the generated components of minerals submarine deposits items in the hopper 2.

Thus, the execution of the specified conditions will allow you to get the guaranteed receipt of the rock mass with a high concentration of the generated components of minerals underwater deposits of elements through the hopper 2 to the crusher 7 and stabilization of the concentration of solid particles in the flow of slurry that is transported from the multi-function system for continuous collection of minerals underwater deposits located on the surface of the reservoir base floating tool, rational configuration of technical means. In this case value of concentration of solid particles in the flow of slurry that is transported from the multi-function system for continuous collection of minerals underwater deposits located on the surface of the reservoir base floating means, the control unit 31 determines by means of the consistometer 28.
