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

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.
