Analysis of manganese distribution of coal seam c 5 of “blahodatna” mine field

Abstract

Purpose. Study of the spatial distribution of manganese in the coal seam c 5 of the “Blagodatna” mine field and the establishment of relationship between its content and the main technological parameters of coal in the region. Methodology. For the purpose of determine the composition of geochemical associations, correlation coefficients (r) between toxic and potentially toxic elements contents were calculated. Elements in which the relationship between the content is described by a correlation coefficient exceeding 0.5 with a significance level of at least 95% were combined into a single geochemical association. During the calculation of correlation coefficients, all values of manganese concentrations were normalized.
