Abstract:
The method using the airlift and the self excited oscillation jet for exploiting deep beach placer has been presented. The physical and mathematical model of airlift is given in this paper. The feasibility of the self excited oscillation pulsed jet as breaker of the airlift is researched. It has been shown theoretically and experimentally that the self excited oscillation pulsed jet not only crushes and looses ore deposit under water, but also lifts particles of solid on the clay and sand bed. The oscillation cross flow caused by the self excited oscillation jet makes particles of solid enter the end of the suction pipe.
