GEO-TECHNOLOGICAL COMPLEX WITH AERO-HYDRODYNAMIC ACTIVATION Russian patent published in 2009 - IPC B03B5/00 E21C41/26 

FIELD: motors and pumps; mining engineering.

SUBSTANCE: geo-technological complex with aero-hydrodynamic activation includes bottom-hole hydraulic washing-out module, rocks fraction separation system, force-feed hydro transportation system, processing complex with dumping system. The geo-technological complex is provided with the mechanical activation module for coarse fractions with movable initiating plant and aero hydrodynamic activation module for middle-size fractions. The aero hydrodynamic activation module is provided with pressurized air supply system being installed in the place of rock bulk material feeding. The pressurized air supply system nozzles are installed shifted and horizontally in a staggered manner. The stationary flat reflecting elements are installed at aero hydrodynamic activation module pit edges and tilted in vertical plane. The above elements are also shifted in horizontal plane with regard to each other. The aero hydrodynamic activation module is linked with fine fraction accumulation module. Radial reflecting elements are installed symmetrically to the stationary flat reflecting elements but shifted horizontally with regard to them along rock mass feeding direction and from the opposite side of pit edge.

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