METHOD FOR SOFTENING AND DISINTEGRATION OF CLAY SANDS AND HYDROMIXTURE SOLID COMPONENT Russian patent published in 2010 - IPC E21C41/30 B03B5/00 

FIELD: mining.

SUBSTANCE: invention relates to mining and may be used for development of natural and technogenic high-clayey gravel deposits of minerals with an increased content of fine-grained and disperse-grained gold. The method involves deposit opening, digging a water supply trench slanted towards the deposit stratum drop and a water collection trench; the accumulator trench is dug between the area under development and the water collection trench. One mounts the suction device of the delivery hydrotransportation installation, mounts an ultrasonic installation relative to the accumulation trench, consistently intensifies filtration of water into the clay sands within the flooded area on the surface and by way of hydrodynamic activation and performs cutting the water saturated sand layers with the hydrodynamic equipment cutter elements, additional hydrodynamic initiation and ultrasonic impact on the hydromixture in the accumulation trench in the low frequencies band providing better effect of hydromixture particles displacement and ultrasound radiation intensity 5 W/cm² or more.

EFFECT: improved efficiency of destruction and disintegration of deposit clay sands.
