Opis (eng)

Izbor optimalne mehanizacije u diskontinualnom sistemu transporta je jedna od najvažnijihodluka koju treba donijeti prilikom projektovanja površinskih kopova. Pri izboru optimalnemehanizacije, uticaj ima veliki broj faktora, kako prirodnih – geoloških i ekoloških, tako itehničkih, ekonomskih i socijanih. Neki od njih se mogu izraziti numerički, u određenimmijernim jedinicama, a neki opisno, lingvističkim varijablama, shodno uslovima koji vladaju narudnim ležištima, a koje karakterišu visok stepen neizvjesnosti i neodređenosti kako prilikomistraživanja, tako i tokom procesa eksploatacije rude. Iskustvo inženjera i eksperata, njihovoznanje i mišljenje, je od ključnog značaja za upravljenje procesima u rudarstvu, shodnoproblematici dinamičkog širenja površinskih kopova u prostoru tokom razvoja radova. Udisertaciji je kreiran integralni model za optimizaciju izbora opreme diskontinualnog sistema,kojim se prevode svi kriterijumi koji utiču na izbor optimalnog rješenja u lingvističke varijable.Izborom metode višekriterijumskog odlučivanjai njenom kombinacijom sa fazi logikom,napravljen je algoritam koji tretira sve pomenute nepreciznosti i nejasnoće prisutne urazličitim rudarskim procesima, a gdje je osnova iskustvo eksperata. Fazi analitički hijearhijskiproces (FAHP) je primjenjen u skladu sa trendom rješavanja problema kao što je izbor rudarskeopreme i upravljanje sistemima. Cijeli algoritam je primjenjen na dvije studije slučaja(površinski kop Ugljevik Istok 1 i ležište L-29C – Bešpelj).

Selecting Optimal Mechanization in Discontinuous Transport Systems is one of the most crucialdecisions to make during the design of surface mines. When choosing the optimal mechanization,a multitude of factors come into play, including natural (geological and ecological),technical, economic, and social aspects. Some of these factors can be expressed numerically inspecific units of measurement, while others are described using linguistic variables, de-pendingon the conditions prevailing at the mining sites. These conditions are characterized by a highdegree of uncertainty and ambiguity during both exploration and ore extraction processes. Theexpertise and opinions of engineers and experts are essential for managing mining processes,especially considering the challenges posed by the dynamic expansion of surface mines overtime. In this study, an integrated model is developed to translate all crite-ria influencing theselection of optimal solutions into linguistic variables. By combining the multiple-criteriadecision-making method with fuzzy logic, an algorithm is created to address theaforementioned uncertainties and ambiguities present in various mining processes, lev-eragingexpert knowledge. The Fuzzy Analytic Hierarchy Process is applied to tackle trending decisionproblems related to mining equipment selection and management systems. The en-tirealgorithm is tested in a real case study involving the Ugljevik East 1 open pit mine and the oredeposit L-29C – Bešpelj., Selecting Optimal Mechanization in Discontinuous Transport Systems is one of the most crucialdecisions to make during the design of surface mines.
