The result of determining the quantitative relationship between the temperature and humidity of enrichment waste materials based on the analysis of digital photographs of laboratory experiments using RGB and Lab methods is presented. Using standard equipment, a laboratory experiment was performed to determine the temperature and humidity of samples of the tailing dam surface layer. Digital photographs of the samples were taken in natural light. The images were processed on a computer to obtain the components value...

The results of numerical simulation of the accumulation of nitrogen oxides in the deadend and main workings during the operation of the mucking and flitting device at the stages of loading and auxiliary operations are presented. The process of accumulation of nitrogen oxides is modeled on the basis of a previously developed two-stage methodological approach: the 1st stage is the calculation of aerodynamic parameters with applying a standard (?? ? ??)-model turbulence and the 2nd stage is the solution of the convec...
