摘要

Based on the assessment of the resource base of Far East region of Russia, the important role of the mining industry for most regions of Far East Federal District was noted. A decrease in the resource potential of geogenous placers has been established, therefore anthropogenic deposits of placer deposits become an important reserve of placer gold mining. Natural and technological factors that need to be taken into account when selecting and applying those technologies and mining equipment that can reduce their influence are as follows: permafrost rocks, high clayey sand deposits, large content of fine and fine fractions of gold, the presence of high content of heavy fractions of other valuable passing components, etc. A number of developed innovative technologies for development of alluvial deposits, as well as new technological equipment for use on dredges and drags, have been noted. The parameters of the technological processes of the jigging machine on the Alaska-35 washing device (USA) have been analyzed, the matrix of interacting factors (such as the shape of the particles of a mineral, particle size, particle density, height of the bed of the jigging machine, frequency of piston swings, stroke of piston, etc.), the purpose of the study is to obtain graph-analytical dependencies for calculating their rational parameters that ensure effective extraction of metals.
