SUBSTANCE: method for hydromechanical benefication involves drilling of production wells, water-jet destruction of a mineral deposit in extraction chambers of the deposit with its changer over to a movable state as a part of a hydraulic mixture, hydraulic lifting via the well to day surface from extraction chambers of the hydraulic mixture in the form of pulp, hydraulic transportation of pulp to a benefication place, and gravitational benefication of the mineral deposit in water medium. Destruction of the deposit is performed during formation of an extraction chamber with a vertical symmetry axis in the form of a rotation figure: cylinder, cone or ball, thus creating a circular flow of coal hydraulic mixture, which is swirled about the vertical symmetry axis, and depositing foreign heavy inclusions and sand at the bottom of the extraction chamber in the created hydraulic cyclone. Suction of coal hydraulic mixture is performed from the level above deposit level; turbulent hydraulic transportation of pulp from the extraction chamber to the place of its preparation for benefication is performed via pipelines. Hydromechanical treatment of pulp is performed so that a brown coal suspension is performed. Target products are obtained in the form of a concentrate of humic acids and a concentrate of bitumens by tangential supply of the flow of the brown coal suspension to a conical sedimentation basin, filling of the sedimentation basin with further settlement of the brown coal suspension and staged pumping-out of highly disperse fractions that are settled subsequently with their supply to different accumulation tanks for collection of target products and benefication tailings. The processing line implementing this method consists of three sections - borehole hydraulic mining, hydraulic transportation and benefication - subsequently dispersing brown coal till fineness.

EFFECT: implementation of staged production of target products.

SUBSTANCE: invention relates to mining and can be used at mining operations. Proposed method comprises drilling the row of test wells to fit downhole hydromining units therein and to washout minerals therefrom by fluid jets forced by said units for pulp to be delivered to surface. Drilled pipes are inclined in the plane perpendicular to spread of said row. Wells are drilled in a row to distance equal to double efficient length of washout jet while rows are spaced apart through distance equal to efficient length of washout jet. Washout is performed from wells towards hanging layer to form the face with hemispherical cross-section perpendicular to well axis.

SUBSTANCE: invention relates to mining and can be used for hydraulic process of coal production. Main and auxiliary openings are driven via tandem and/or single faces that delineate blocks, barrier and safety pillars. Water is forced into faces by pump stations after cleaning at drainage complexes, mechanised settlers and/or water headers. The latter are located in intercommunicated chambers located at lower points of hydraulic site blocks and exiting into accumulation openings via which hydraulic transport is performed and rock is discharged. Abandoned pillars are liquidated after working of extraction pillar at backstroke in tow-side or single-side cuts. Water is cleaned at mechanised settlers and/or water headers with application of combination of water cleaning technical means and processes. For this, used are, for example, water impermeable partitions with water bypass nearby bottom, thin-layer clarifiers, flotation, coagulation, water processing by constant pulsating current, etc.

SUBSTANCE: invention relates to mining and can be used for hydraulic borehole mining of minerals. Proposed method comprises opening of the deposit via central and peripheral wells, placing the equipment therein and opening of adjacent chambers in layers, from bottom to top, starting from peripheral chambers. Prior to opening of the next layer through the entire bed thickness, undercut chamber is formed nearby soil of formed chamber and, parallel with said layer, of artificial ceiling of hardening material with inclination to centre. Shrinkage of fallen rock and filling of opened space with hardening material, opening and backfilling of central chamber at development of every chamber. After making of said artificial ceiling, several hydraulic cuts are made over the height of temporary wells. After formation of undercut space, rocks are hydraulically fractured from lower hydraulic cuts to force fluid into fracture unless rock failure into undercut space. Caved rock is partially flooded by hydraulic fracture fluid and giants to wash out the rock. As rock disintegrates, pulp is fed to the surface. As magazine level drops below design mark, hydraulic fracturing is repeated from hydraulic cut closest to stripped area, shrinkage, wash-out and discharge of pulp. Then, said jobs are repeated unless stripped area reaches aforesaid artificial ceiling. Now, shrunk rock is completely washed put, pulp is discharged and stripped area is filled.

EFFECT: selective extraction, decreased losses of minerals and costs, lower environmental effects.

SUBSTANCE: proposed method comprises exposure of producing formation by production well equipped with jetting equipment and jetting of minerals. Nearby soil of developed strata horizontal drain hole is drilled for preliminary drying of working zone and creating conditions for operation of jetting in air. Note here that minerals are broken by jetting, gravity and increasing rock pressure resulted from underground water level decrease. This allows mining the minerals at strength of 3-5 MPa. Light grade well is drilled in vertical plane with drain well inclined to mouth to allow outflow of hydraulic mix by gravity and accumulated in settler. Operation of wells of hydromining complex is performed in turns. First, drain well is activated. After water level drop below giant jet nozzle, giant jet is activated. Minerals are mined by intervals in direction from bottom to mouth of operation well and with withdrawal of casing tubes.

SUBSTANCE: first preparatory field mines are driven - level haulage and ventilation drifts with identical geodetic elevations, block crossdrifts and accumulating drifts with an inclination for a self-flow transport, stripping wells are drilled at the right angle to the bed plane, then, line cuts are washed by the hydraulic method. Level haulage and ventilation drifts stretch at identical geodetic elevations to form a ventilation scheme with horizontal depression. The area of line cuts is increased to initiate the process of caving of a hanging massif in a stope. The stope bottom is formed by washing of line cuts with an inclination providing for accumulation of caved coal through self-flow. The caved coal is magazined to control shift of side rocks in the stope. Chambers that are adjacent to the mined space are separated by barrier sight pillars. Oversize material is crushed, and coal mass is periodically discharged in dosing manner into the accumulating drift to provide for stope bottom movement up the pitch.

EFFECT: elimination of air leaks through a mined space, reduced contamination of coal by caved rocks, higher reliability of breaking face functioning and labour safety.
