Abstract
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.
Highlights
Russian Far East has rich and diverse natural resources
3 Results In Institute of Mining of Far East Division of Russian Academy of Sciences, for several years, studies were carried out to create samples of mining equipment that enhance the extraction of gold from placer deposits
The prospect of using the dredging technology for the development of anthropogenic placers underwater has been determined, and equipment has been developed to increase the extraction of large fractions of the valuable component from the rock floor of the deposit
Summary
Russian Far East has rich and diverse natural resources. In a number of its regions, the mining industry is practically the only sector of the national economy.The main types of minerals, which are mined in Far East, are gold, platinum, silver, diamonds, tin, lead and zinc, tungsten, coal, boron, fluorite, oil and gas.Far East takes the second in terms of explored balance reserves of gold, and the first place in Russia for mining from subsoil. Russian Far East has rich and diverse natural resources. The main types of minerals, which are mined in Far East, are gold, platinum, silver, diamonds, tin, lead and zinc, tungsten, coal, boron, fluorite, oil and gas. Far East takes the second in terms of explored balance reserves of gold, and the first place in Russia for mining from subsoil. In forecasted resources, the leading position currently belongs to core gold (81.3%), with a substantially subordinate value of placer (13.4%) and gold in complex deposits. 3,305 gold deposits were registered on the territory of the federal district, of which 180 indigenous (including 14 complex) and 3,153 alluvial deposits. The largest number of alluvial deposits is located in Magadan Region (39%) and Republic of Sakha (24.3%), Chukotka Autonomous District - 12.1%, Khabarovsk Region - 10.3% and Amur Region -
