Dynamics of succession processes on sulphide-containing mine dumps as a result of their optimization

Abstract

When optimizing the relief at the top of the trapezoidal sulfide-containing mine dump, young soil (embryozem) was formed as a result of abio- and biotic factors. In parallel with the formation of embryozems, primary succession processes are developing. As a result, the species composition of vegetation, the staging and intensity of progressive succession were studied depending on the mesorelief of dumps in accordance with the weathering and soil formation processes developing over time. The properties and indicators of young soil in depressions and sulfide rock (control) 25 years after the completion of the dumping of the rock pile were studied. As a result of optimization at the top of the dump, the processes of formation of embryozems in the depressions are significantly accelerated.
