GEO-TECHNOLOGICAL COMPLEX WITH HYDRODYNAMIC AND LASER INITIATION Russian patent published in 2009 - IPC B03B5/00 E21C41/26 

FIELD: motors and pumps; mining engineering.

SUBSTANCE: geo-technological complex with hydrodynamic and laser initiation includes hydro washing-out module for bottom hole, rocks fraction separation system, force-feed hydro transportation system, processing complex with dumping system. The complex is provided with electro-thermal release module for structural links in large extra-heavy rocks fractions. The electro-thermal module releases the above structural links by the laser initiation plant and module for hydrodynamic crashing of middle-size and small-size fractions. The structural links are released by the laser initiation plant, which is movable in vertical direction due to swing drive and movable in horizontal direction due to displacement drive along the gantry. Module for hydrodynamic crashing of middle-size and small-size fractions is installed on the gantry so that it can displace along the above gantry. It is provided with periodic pressurised water supply system and flat rotary reflecting elements. The pressurised water supply system nozzles are installed rigidly and at an angle to the vertical plane regarding each other. The nozzles are shifted in the horizontal plane. The flat rotary reflecting elements are linked in pairs with the displacement system and installed between the pressurised water supply system nozzles so that they can turn around axis in the vertical direction.

EFFECT: increased effectiveness of sandy and clay rocks state and properties change.
