ECOLOGICAL BASIS OF BIOLOGICAL RECULTIVATION OF DUMPS OF DIAMOND DEPOSITS IN YAKUTIA

The article presents the results of the studies of surface, soils and vegetation of diamond mines piles and experimental work on biological remediation. Yakutia produces 97 % of all diamonds in Russia, and its world market share is 25 %. Open mining led to the formation of large open cuts, waste rock dumps, tailings ponds. If no recultivation is provided, the permafrost conditions may increase these areas by many times.
