| Summary: | Many researchers have found that the nature of the grain size distribution makes it possible to assume the regularity of such a distribution, despite the difference in the physical properties of minerals. There are quite a large number of approximating functions for describing the regularities of the separation of coal and mineral complexes by size, obtained experimentally. There is a need to develop a new methodological approach and tools for selecting the best approximation function. The paper presents the results of predicting the total size characteristics of anthracites of the Krasnogorsky mine by the RRSB, Pogosov, and Weining functions. The quality of the approximation is estimated by the value of the standard deviation. It is established that the Weining formula allows us to calculate with a minimum error the granulometric composition of anthracites of the named deposit in the range of fineness from 0 to 150 mm. |
