GEOTHERMAL CONTROL OF THE BASES OF SUPERFICIAL CONSTRUCTIONS DIAMOND-MINING MINES OF YAKUTIA
In the present article materials on features of geothermal control of the bases of superficial constructions on underground mines AC «ALROSA» are presented. The analysis of researches on development of deformations of a ground at temperature change around mouth parts of mine trunks has shown that the greatest influence render rheological processes in a zone frost penetration-thaw through. The three-dimensional mathematical model of heat exchange materials under the basis tower which allows to consider real process frost penetration-thaw through poral a solution of a frozen file in a spectrum of possible temperatures at change thermophysical properties and the general salinity of a cut of breeds on depth is developed. On diamond-mining mines in Yakutia constant operation of systems compulsory frosts materials near to trunks and all cooling system of pile fields is necessary, and calculations of bearing ability of the cryogenic bases should be carried out taking into account actual watering and salinities of a pedigree file.
