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

FIELD: mining industry.

SUBSTANCE: said geotechnological complex for gold dredging and placer mining incorporates a module for preliminary disintegration and hydroerosion of rock in the face with guiding shields, a disintegrating module located below the level of grooved trench for rock hydraulic transportation, a processing complex with hydrotransportation systems and waste dumping system. The disintegrating module has a chute located inside the closed loop of trench for disintegrated rock accumulation. The chute is directed along the rock inflow for rock hydrotransportation and is sloped in the direction of waste dumping. Along the chute and over it, a rigidly supported trestle is installed. The trestle is provided with a bucket driven along the cross beam for rock disintegration. On both sides of the chute, at an angle, transverse flaring chutes with rigidly wall-mounted disintegrators are installed.

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