The research of the phosphogypsum granulometric composition and the patterns of its reconstitution in the aggradiational waste disposals

Abstract

The mechanical characteristics of the stocked into dump massives dispersed rocks influencing the slope stability is strongly determined by slopes’ granulometric composition. Due to the phosphogypsum specific characterics, it may be difficult to choose the proper methodology for its’ granulometric composition studying. This article is dedicated to the comparative analysis of the results of the different methods’ usage for granulometric composition of this material in the aggradiational waste disposals research. Additionally the problem of aggradiational phosphogypsum homogeneity in such structures has also been studied by determining the presence of fractionation and rock strength parameters’ in the ash pond beach variability.
