Analiza mogućnosti povećanja kapaciteta otkopavanja rude bakra na površinskom kopu Južni Revir Majdanpek na 11x106 tona godišnje
Analysis the possibility of increasing capacity of copper ore mining at the open pit South Mining District Majdanpek at 11x106 tons annually
Projekat: Istraživanje i praćenje promena naponsko deformacionog stanja u stenskom masivu "in-sity" oko podzemnih prostorija sa izradom modela sa posebnim osvrtom na tunel Kriveljske reke i Jame Bor (MPNTR - 33021)
Sažetak
U radu je izvršena analiza mogućnosti povećanja kapaciteta na površinskom kopu Južni revir sa aspekta ostvarivanja maksimizacije neto sadašnje vrednosti. Analiza se bazira na kretanju diskontovanog novčanog toka tokom eksploatacionog perioda od 18 godina. Za ovo sagledavanje korišćen je savremeni pristup projektovanju površinskih kopova primenom softvera Whittle i Gemcom Gems. Analiza je pokazala pozitivno kretanje diskontovanog novčanog toka od treće godine do kraja analiziranog perioda, pri čemu se ostvaruje neto sadašnja vrednost u iznosu od 596.252.546 $.
Abstract
The paper analyzes the possibility of increasing capacity at the Open Pit South Mining District in terms of achieving maximum net present value. The analysis is based on the movement of discounted cash flow during exploitation period of 18 years. The modern approach of designing the open pits was used for this consideration using the software Whittle and Gemcom Gems. The analysis showed a positive trend of discounted cash flow from the third year until the end of analyzed period in achieving the net present value in the amount of 596 252 546 $.
