TO THE QUESTION OF INCREASE OF EFFICIENCY OF DEVELOPMENT OF GEORESOURCE POTENTIAL OF DEPOSITS OF DIAMONDS IN THE SOUTHWEST OF YAKUTIA
Diamonds production in АC «ALROSA» are characterised by complication of mountain-geological and mining conditions of development of radical deposits of diamonds of Yakutia, thus there is a transition from an open way of working out − to underground geotechnologies. The choice of an optimum variant of system of working off concrete kimberlite tubes depends on set of factors, mountain-geological conditions, the maintenance and cost of diamonds in ore are basic of which, the general reconnoitered and look-ahead stocks etc. are necessary for carrying out the Definitive choice of a variant of system of working out of a deposit with division into separate stages at the established time indicator and volumes preparatory and добычных works. Economic criteria with the additional restrictions reflecting is minimum admissible cost level of a commodity output at this or that system of working off алмазоносной of a tube are thus considered. For a tube "International", as well as on a tube "the World", located in a southern part of the Western Yakutia, occurrence high-water, water-bearing a complex it was more effective to fulfil an interval open-cast mines at a final stage of development of deposits, after extraction of all stocks on deep horizons in the underground way that would lead to essential economic benefit.
