METHOD AND DEVICE FOR DUST CONTROL IN TAILING PIT BEACH Russian patent published in 2006 - IPC E21F5/02 

FIELD: mining, particularly methods and devices to prevent dust generation in tailing pit benches by moistening thereof with water or liquid binding agent.

SUBSTANCE: device comprises self-moving vehicle, for instance pontoon water craft, provided with pump, vessel for reagent, hydraulic monitor, unit with executive tool for channel forming in bank area and isolated power generating plant. Above mechanisms are installed on water craft deck. Hydraulic monitor may rotate in horizontal and vertical planes. Drives of all mechanisms are linked with the power generating plant. Executive tool is installed below water craft floating line. Vessel for reagent is provided with proportioning device. Dust control method involves initially installing the water craft on tailing pit water surface; directing the water craft towards bank to area to be sprayed, in which working tool forms channel for water craft movement; pumping water from tailing pit into hydraulic monitor; adding reagent from vessel to water with the use of proportioning device and spraying the obtained liquid over dust-forming area. Water from tailing pit is used for above spraying operation and for water craft movement.

EFFECT: increased dust control efficiency.
