ESTIMATION OF PECULIARITIES OF TEMPERATURE INVERSION FORMATION IN OPEN MINING IN THE ARCTIC CONDITIONS

Abstract

The article presents the results of studies on the study of the effect of temperature in-versions on the efficiency of ventilation of a quarry space. It was found that a negative tem-perature difference leads to cooling of the surface air layers, which can cause the accumula-tion of cooled air masses in the lower part of the open pit and a decrease in the intensity of air exchange. It is shown that the assessment of the peculiarities of the formation of the pa-rameters of the mine atmosphere and the substantiation of the boundaries of the use of natu-ral ventilation of gold-ore quarries, taking into account the steady-state temperature gradi-ent, can be carried out using mathematical modeling based on the Ansys Fluent software package.
