Priprema ležišta za eksploataciju primenom podetažne metode otkopavanja otkopavanja sa zapunjavanjem
Mirko Kurdulić (2024)Rudarstvo je ključna grana industrije koja obezbeđuje osnovne sirovine neophodne za razvoj savremenih tehnologija i infrastrukturnih projekata. Sa razvojem tehnoloških inovacija i povećanjem globalne potražnje za mineralnim resursima, efikasnost i bezbednost u rudarstvu postaju prioriteti. Ovaj diplomski rad istražuje aspekte koji se odnose na optimizaciju, analizu i unapređenje tehnika eksploatacije i obrade mineralnih resursa, sa posebnim fokusom na pripremu ležišta za eksploataciju primenom podetažne metode otkopavanja sa zapunjavanjem otkopa.Podetažna metoda otkopavanja sa zapunjavanjem otkopa u radu će biti analzirana ...rudarstvo, priprema ležišta, optimizacija, eksploatacija, podetažne metode, zapunjavanje, životna sredina...

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.

Analiza primenjenih metoda za transport parafinske nafte
Dunja Milojević (2024)Sadržaj parafina u nafti ima dominantan uticaj na svojstva parafinskih nafti. Taloženje parafina, odnosno taloženje čvrstih čestica parafinskog voska, predstavlja ozbiljan globalni problem tokom proizvodnje i transporta sirove nafte. Samo taloženje voska zavisi od termodinamičkih faktora, poput temperature, pritiska i sastava nafte. Transport nafte cevovodima je uobičajeni proces transporta u naftnoj industriji. Kada prilikom cevovodnog transporta parafinske sirove nafte, dođe do prekida protoka i hlađenja nafte ispod temperature stinjavanja, parafini će kristalisati, pri čemu će doći do, geliranja celokupne transportovane ......

Production of morphological dictionaries of multi-word units using a multipurpose tool
The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed. We also offer an evaluation ...electronic dictionary, Serbian, morphology, inflection, multi-word units, noun phrases, query expansion... subsections IV-B and IV-C, the evaluation results were classified as follows: Fig. 6.

Моделирање дисперзије прашине у фази одлагања флотацијске јаловине у руднику “Шупља стијена”
Вања Живановић (2024)Рударство, као једна од кључних индустрија у многим земљама света игра важну улогу у стварању економске вредности али истовремено и велики притисак на животну средину. Процеси експлоатације и обраде руде често укључују употребу разних хемикалија, што може изазвати загађење земљишта, воде и ваздуха. Очување животне средине постаје све важније питање у свету у којем се суочавамо са изазовима као што су климатске промене, деградација земљишта, губитак биодиверзитета.
