The question of the overburden rock dump formation during the development of iron ore deposits of Ukraine was considered. An analysis of the technology of forming a high single-tier dump in an abandoned deep pit was carried out. Two technology options are considered: loading rock on the slope of high single-tier dump and on its edge. The influence of the dependence of the loading rock on the edge of high single-tier dump on its stability of a has been established. The nature of the change in the width of the possible landslide prism, the safe distance of the dragline location has been established. The prospects for the formation of a high single-tier dump in the regime of controlled deformations are substantiated. For high single-tier dump the ordinary method of slices was justified and used to calculate the safety factor. Recommendations on the use of draglines available in Ukraine for forming the high single-tier dumps of overburden rock have been issued.

W artykule rozważono kwestię powstawania nadkładu skalnego podczas eksploatacji złóż rudy żelaza na Ukrainie. Przeprowadzono analizę technologii formowania zwałowiska wysokiego jednopoziomowego w nieczynnym wykopie głębokim. Rozważane są dwa warianty technologiczne: załadunek skały na zboczu wysokiego zwałowiska jednopoziomowego oraz na jego krawędzi. Określono wpływ zależności skały obciążającej od krawędzi zwałowiska wysokiego jednopoziomowego na jego stateczność. Ustalono charakter zmiany szerokości ewentualnego graniastosłupa osuwiskowego oraz bezpieczną odległość położenia liny zgarniającej. Możliwości powstania wysokiego zwałowiska jednopoziomowego w reżimie kontrolowanych deformacji są uzasadnione. Dla wysokiego zrzutu jednopoziomowego zasadna była zwykła metoda przekrojów, wykorzystana do obliczenia współczynnika bezpieczeństwa. Wydano zalecenia dotyczące wykorzystania dostępnych na Ukrainie koparek do formowania wysokich jednopoziomowych zwałów nadkładu.
