Abstract
The Siberian Federal District of the Russian Federation has a significant number of placer gold deposits, composed of rocks with considerable clay content. The long time required for settling fine particle fraction of jet-broken mass leads to supplying pressure water with significant amounts of fine particles to the hydraulic monitor units. Based on the previous studies, the solutions are proposed that can be applied in developing deposits with rock jetting, water reuse from settling ponds, and significant amounts of fine particles in the developed soils. Based on these solutions, rock jetting can be conducted for both overburden and mining operations. For mining operations, it is recommended to limit the content of fine soil particles in pressure water to 60 g/l, and for overburden operations – to 100 g/l. A distinctive feature of these technological solutions is the process water supply to the hydraulic monitor with a controlled amount of fine soil particles in its composition. The accumulation of these particles in process water occurs naturally during the flushing season.
