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...

Flyrock Induced by Blasting in Surface Mining
Milanka Negovanović, Lazar Kričak, Snežana Ignjatović, Stefan Milanović, Jovan Marković, Nikola Simić, Rade Šarac (2022)Минирање представља и даље најефикаснији и најјефтинији начин експлоатације великих количина чврстих минералних сировина на површинским коповима. Енергија експлозије се користи за фрагментацију чврсте стенске масе до захтеване гранулације. Поред позитивних ефеката минирања, постоје и одређени нежељени ефекти сваког процеса минирања који се могу јавити, а то су: потреси тла, разлетање комада стене, ваздушни удари, отровни и загушљиви гасови и прашина. Разлетање комада стене је неконтролисано избацивање фрагмената одминиране стенске масе и представља један од главних извора материјалне ...Milanka Negovanović, Lazar Kričak, Snežana Ignjatović, Stefan Milanović, Jovan Marković, Nikola Simić, Rade Šarac.

Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules
The stability analysis of homogeneous rock slope following the Hoek–Brown failure criterion under the hypothesis of different flow rules is performed based on limit equilibrium and finite element methods. The applied failure criterion is the generalized Hoek–Brown that can be introduced as a shear/normal function in analysis applying different flow rules. The results are compared with those obtained by the application of equivalent shear strength parameters of the Mohr–Coulomb criterion, considering that this is still the most widely used ...Kružna klizna površ, Huk-Braunov kriterijum loma, Kriterijum popuštanja, Smičuća/normalna funkcija, Nivo napona, Verovatnoća i parametarska analizaSvetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón .

E-Connecting Balkan Languages
In this paper we present a versatile language processing tool that can be successfully used for many Balkan languages. This tool relies for its work on several sophisticated textual and lexical resources that were developed for most of Balkan languages. These resources are based on several de facto standards in natural language processing....

The shear strength evaluation of rough and infilled joints and its indications for stability of rock cutting in schist rock mass
Construction of E75 highway section through Grdelica gorge was one of the most demanding projects realized in recent Serbian history. The alignment approximately 25 km long consists of several tens of bridges, two tunnels, three galleries and cuts with total length of 6 km. The alignment passes through highly anisotropic Palaeozoic schist rock formation of different weathering grades. This study focuses on shear strength properties of discontinuities, which are found to be the critical feature contributing to the occurrence ...Dušan Berisavljević, Zoran Berisavljević, Svetlana Melentijević.

Probabilistic analysis of anisotropic rock slope with reinforcement measures
During the construction of E75 highway through Grdelica gorge in Serbia, a major failure occurred in the zone of reinforced rock slope. Excavation was performed in highly anisotropic Paleozoic schist rock formation. The reinforcement consisted of the two rows of micropile wall with pre-stressed anchors. Forces in anchors were monitored with load cells while benchmarks were installed for superficial displacement measurements. The aim of the study is to investigate possible causes of instability considering different probability distributions of the ...Zoran Berisavljević, Dušan Berisavljević, Miloš Marjanović, Svetlana Melentijević.

Tektonska evolucija istočne periferije timočke eruptivne oblasti
Stefan Zujić (2024)U radu su predstavljeni rezultati proučavanja tektonskih i litostratigrafskih karakteristika istočnog oboda Timočke eruptivne zone. Zaključci o geološkim odnosima u okviru Timočke eruptivne oblasti i susednih geotektonskih jedinica izvedeni su na osnovu podataka prikuljenih tokom terenskih istraživanja i podataka dobijenih iz publikovanih radova. Rezultati rada ukazuju da je teren koji je bio tema ovog istraživanja, u strukturno-tektonskom smislu oblikovan tokom glavnih geodinamičkih događaja u okviru Karpato-balkanskog orogenog luka. Analizom strukturnog sklopa su utvrđeni glavni deformacioni događaji koji su predsavljeni ...Stefan Zujić. Tektonska evolucija istočne periferije timočke eruptivne oblasti, 2024
