Prostorni položaj ofiolita istočne Vardarske zone: geofizičko-geološki model i njegove geodinamičke implikacije
Dragana D. Petrović (2015-12-29)Centralni deo Balkanskog poluostrva je geotektonski veoma složen. Tetis je zatvorentokom gornjeg mezozoika, a ofioliti na zapadu i ofioliti Vardarske zone predstavljajuostatke nekadašnjih okeanskih prostora. Najistočniji deo Vardarske zone razlikuje se odsvih ostalih ofiolita na Balkanskom poluostrvu i karakteriše se najizraženijim suprasubdukcijskimafinitetom. Istočna vardarska zona locirana je u centralom delu Srbije.Na severu se prostire do Apusena u Rumuniji, a na jugu obuhvata cetralni deoMakedonije i Peonias zonu u severnoj Grčkoj. Istočna vardarska zona se nalazi istočnood geotektonske jedinice Kopaonik ...... Special Publication, 260, 155-178. Kissel, C., Speranza, F., Islami, I., and Hyseni, A., 1995.

Prognoza operativne efikasnosti aktivnog podzemnog rudnika zasnovana na teoriji sivih sistema
Svetlana M. Štrbac-Savić (2016-06-10)Efikasnost predstavlja preduslov za opstanak svake rudarske kompanije, posebno u uslovima izuzetno konkurentnog trţišnog okruţenja kao što je to rudarska industrija. Efikasnost oznaĉava sposobnost kompanije da ispuni svoje kratkoroĉne ili dugoroĉne ciljeve. Operativna efikasnost se definiše kao odnos izmeĊu ulaznih parametara potrebnih za odvijanje proizvodnje i pokazatelja dobijenih proizvodnjom. U kontekstu rudarskog poslovanja, operativna efikasnost se odnosi na vreme potrebno da se mineralno dobro transformiše u novĉana sredstva. Visoka operativna efikasnost se postiţe kada se ostvari prava kombinacija karakteristika ...podzemni rudnik, operativna efikasnost, prognoza, teorija sivih sistema, stohastiĉke diferencijalne jednaĉine, simulacija... ac.rs/~ssegan/MonteKarlo.pdf [WANG98] Yiding Wang, Guoxiong Zhang, Kee S.

Multiple-Criteria Decision-Making in Mine Development Planning
Sanja Bajić (2023)The Borska Reka ore deposit is an experimental location where developed methodologies have been applied. It is the largest ore body within the Bor mining complex, which has been the subject of numerous studies and analyses for more than three decades. The paper focuses on the application of FAHP and the VIKOR method to address ranking of alternatives and select the optimal mining method by means of fuzzy multicriteria optimization.Sanja Bajić.
