GEOTECHNOLOGICAL DREDGE COMPLEX WITH TERRACE PLACER DEVELOPMENT DEVICE Russian patent published in 2009 - IPC E21C45/00 

FIELD: mining.

SUBSTANCE: invention refers to combined development of gold placers using mini-dredges. Complex consists of a dredge with a stacker and installations meant for deep processing of sandy and clay rock of gold placers, a high-head hydromonitor device with a system controlling the barrel movement in a vertical plane, and a hydraulic transport free-flow system. Complex is equipped with a bridge rigidly fixed in the dredge nose part. Bridge is provided with a round divertor intended for movement, and a round divertor meant for a support, which are rigidly fixed on the bridge posts. High-head hydromonitor device is installed on a base rotated by means of a drive. Rotary base is hinged to the platform and equipped with linear guideways. Platform is equipped with a drive of linear guideways which are connected with a round divertor intended for movement, and provided with an additional support connected with round divertor meant for the support.

EFFECT: intensifying mining process including development of terrace high-level placers.
