OPTIMISATION OF CONTROL SYSTEMS BY STABILITY TOWER ON DIAMOND-MINING MINES IN YAKUTIA
In the present article, materials on optimization of control systems by stability tower on underground diamond-mining mines AC «ALROSA» are presented. By researches on development of deformations of breeds at change of temperatures, it is established that the greatest influence render rheological processes in a zone frost penetration-thraw through. According to recommendations for effective expose to frost soils it is necessary to accept temperature of a cooling liquid equal – 20 °С. The maximum temperature soils at which it is possible to begin loading on the basis tower makes not above – 7 °С. In construction operation, taking into account heterogeneity soils and their salinities, the temperature in controllable points should be supported at level – 12–13 °С. The developed three-dimensional mathematical model of heat exchange soils under the basis tower has shown that freezing system depending on cooling and air temperature in a trunk it is recommended to be maintained in a cyclic mode. The received values of temperatures of breeds around an arrangement of piles of the base tower should will be verified with results of modelling, and if necessary to correct work of cooling devices for maintenance of demanded temperature conditions.
