Abstract

Currently Belaruskali develops deep-level potash salt reserves of the Starobinsk deposit. Rock mass temperature reaches +25 °С, and, considering heat emission of high-capacity mining equipment, mine air temperature rises up to +35 °С. As a consequence, labor conditions of miners are uncomfortable, and equipment can cut out because of thermal overload. This article presents experimental research findings on microclimate in mine roadways and characteristics of heat emission sources in deep-level mining of potash reserves. Based on the experimental data and using the analytical system AeroSet, the heat and ventilation models are constructed for development entries and production headings in the study area. Numerical modeling of thermal control efficiency in longwalls is performed. It is found that the most efficient activity is air conditioning. The microclimate normalization system is substantiated during the research. The developed technology for mine air conditioning ensures normalization of microclimate in longwalls and cooling of power equipment. The authors describe the developed air conditioning system, report its test data and mark out further research to improve microclimate normalization systems in deep-level mines of Belaruskali.
