The disadvantages of this method are the low efficiency and the complexity of the technology, process intensification of production in the development of high-clayey placers, as well as the negative environmental impact of this technology on the environment.

There is a method of hydraulic borehole mining of minerals, for which the set of equipment used with softening rock energy component and the generator of elastic oscillations to maintain the breed in the steady state to violate thixotropy (transition in the plastic condition of the breed in the initial coherent state after discontinuation of mechanical impact) /3/.

The set of tools used in this way, allows to solve the problem of loosening and stability of rock at its transition from fragile what about the plastic state. However, the phase contained in the viscous state, and represents a structured and an unstructured liquid remains in an unstable state, because clay particles have a pronounced tendency to coagulate.

In addition, the strength properties of rocks vary in a wide range, the ratio of the fortress on Protodyakonov argilite 3-6, the compressive strength of from 100 to 800 kg/ cm2at Sandstone coefficient fortress on Protodyakonov - 1,3-7,8, the compressive strength of from 390 to 1660 kg/cm2. This creates additional technological problems.

The technical result of the proposed solution is to increase the efficiency of process development the minerals by transferring productive rock mass in mobile and dispersed condition by mechanical and ultrasonic effects.

The technical result is achieved due to the fact that geotechnological complex hydraulic borehole mining, comprising a platform, monitor the installation with a telescopically movable head, airlift, a rotary device mounted on the platform, the water recycling system, equipped with a system of generation of elastic waves and switchgear associated with feeding elements of air and ultrasonic disintegrator, and monitor the plant is equipped with automatic control system of jetting installed on an additional platform and connected to the rotary device monitor setup through the hydraulic system, thus becoming vertical jet installation is equipped with a rigid latches included in the interaction with the slots additional vertical rod, and the system generation elastic waves made with the possibility of receiving the vibrations of ultrasonic frequency variable power transmitted through the converters on the emitter zone of erosion, the emitter zone preliminary disintegration and the emitters of ultrasonic disintegrator first and second levels, with additional vertical rod jetting installed sensors fixing the dynamic properties of the environment of the zone of erosion and sensors fixing the dynamic is ski properties of the medium zone preliminary disintegration, related through numerical pre-transformation with the control system operating parameters of the ultrasonic generator and an automatic system to control the operation of the monitor, and the input and output of the ultrasonic disintegrator installed sensors dynamic properties of the environment of the cage associated with the control system operating parameters of the ultrasonic generator through numerical device process subsequent disintegration.
