GEOTECHNOLOGICAL COMPLEX FOR GOLD DREDGING AND PLACER MINING Russian patent published in 2008 - IPC E21C41/30 B03B5/02 

FIELD: mining industry.

SUBSTANCE: said complex is provided with a supported trestle and an ultrasonic and mechanical tumbling module. Rotatable ultrasonic radiation module is connected to movable carriage rim by means of a hub and sliding supports. The movable carriage is provided with a drive for moving it along the trestle cross beam and a drive for turning the ultrasonic radiation module around the movable carriage yoke axis. The rotatable ultrasonic radiation module has drives for moving the ultrasonic sources in the vertical plane, a dual drive for moving the ultrasonic sources in horizontal plane, sensors to determine the rock physical and mechanical state, and communication links with functional module of disintegration process automatic control system.

EFFECT: improved efficiency of mining due to intensification of disintegration of rock with complex physical and mechanical properties during dredging and placer mining.
