The Tailings Storage Facility Veliki Krivelj was formed by damming the Krivelj River valley, and it constitutes one of the largest industrial waste disposal sites in Serbia. As such, it represents a big challenge for the Bor Copper Mine in terms of stability preservation and environmental protection. Bering this in mind, it is safe to say that it is of crucial importance to recognize all the risks involved with its operation and management. This paper presents a semi-quantitative assessment of the risks entailed In the management of Tailings Storage Facility Veliki Krivelj, and demonstrates the use of 4×4 risk matrix to estimate the likelihood of potential failure scenarios and consequences and includes the application of the „As Low As Reasonably Practicable“ diagram for final risk evaluation. The results show that the management of the Tailings Storage Facility Veliki Krivelj is associated with risks that vary from negligible to high, i.e. from broadly to conditionally acceptable risks and also suggest that the irregularities in hydraulic elements and hydro-technical structures at Tailings Storage Facility are the ones with the greatest impact in increasing the risks.

Składowisko odpadów poflotacyjnych Veliki Krivelj powstało w dolinie po przegrodzeniu tamą rzeki Krivelj, w chwili obecnej jest to jedno z największych składowisk odpadów przemysłowych na terenie Serbii. W sowim obecnym kształcie stanowi ono wielkie wyzwanie dla zakładu kopalnictwa miedzi Bor, w zakresie ochrony, zachowania i stabilizacji warunków środowiska naturalnego. Mając powyższe względy na uwadze, stwierdzić należy że kwestią absolutnie kluczową jest rozpoznanie wszelkich rodzajów ryzyka związanego z funkcjonowaniem i utrzymaniem wysypiska. W artykule przedstawiono w pół-ilościową analizę ryzyka związanego z funkcjonowaniem składowiska odpadów poflotacyjnych Veliki Krivelj. Zademonstrowane zastosowanie macierzy ryzyka 4×4 do obliczania prawdopodobieństwa awarii w kilku rozpatrywanych scenariuszach działania oraz towarzyszących im skutków. Przedstawiono także zastosowanie diagramu obliczania ryzyka końcowego według schematu „tak niskie, jak tylko praktycznie wykonalne”. Wyniki wskazują, że funkcjonowanie składowiska odpadów poflotacyjnych Veliki Krivelj związane jest występowaniem wielu czynników ryzyka, od pomijalnych do bardzo wysokich poziomów, innymi słowy, od ryzyka powszechnie akceptowanego do czynników akceptowanych warunkowo. Wskazano także, że nieregularne działanie elementów hydraulicznych i hydro-technicznych w ramach urządzeń składowiska stanowi czynnik mający największy wpływ na podniesienie poziomu ryzyka.
