  • Просторна анализа епикарста у оквиру карстног система источног дела Суве планине

    Бранислав Петровић, Зоран Стевановић, Вељко Мариновић, Снежана Игњатовић (2022)
    Епикарст представља највиши део стенске масе који је изложен карстификацији, при чему су главне карактеристике епикарста акумулирање подземне воде и стварање услова за формирање концентрисаних токова у подини ове зоне. У досадашњој пракси истраживања епикарста углавном су коришћене индиректне методе: даљинска детекција, анализа хидрограма карстних врела, хидрохемијске и изотопске анализе, па чак и опити трасирања, док је са друге стране јако мали број истраживача изучавао епикарст директним теренским истраживањима. У раду je приказана иновирана методологија истраживања епикарста, која користи ...

    Mogućnost povećanja korišćenja resursa čvrstog energetskog goriva u procesu rešavanja energetske krize koja je sve prisutnija u širem regionu, jeste pravi izazov rudarske nauke. Podzemna eksploatacija uglja je složen proizvodni proces koji objedinjuje više tehnoloških postupaka u jedinstvenu celinu: izradu podzemnih prostorija, otkopavanje, transport i izvoz, ventilaciju proizvodnog sistema, odvodnjavanje, servisiranje objekata i sistema, zaštitu i sigurnost rada. Jedan od osnovnih problema koji prati podzemnu eksploataciju uglja jeste stabilnost podzemnih prostorija i deformacije na površini terena, jer su podzemne ...

  • Application of softwares for drilling and blasting

    Stefan Milanović, Lazar Kričak, Milanka Negovanović, Nikola Simić, Jovan Marković (2019)
    U današnje vreme softveri se sve više primenjuju u rudarstvu kroz eksploataciju mineralnih sirovina, projektovanje rudnika, u obavljanju različitih operacija na terenu i sl. Među softverima za rudarstvo, postoje softveri za specifične rudarske operacije, kao što su operacije bušenja i miniranja. Ovi procesi su veoma važni u eksploataciji čvrstih mineralnih sirovina, jer predstavljaju najjeftiniji i najefikasniji oblik fragmentacije stenske mase. Kroz rad, predstavljeni su neki od softvera u kombinaciji sa modernim tehnologijama, koje se koriste širom sveta i koje ...

  • Using gravity data to define structural correlation affecting the formation of Neogene basins

    Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović (2023)
    A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...

  • Determining seismic hazard in slowly deforming region: Can we gather enough information from karst caves?

    Ana Mladenović, Jelena Ćalić (2021)
    Methods to determine seismic hazard in any region vary depending on the regional seismicity, but can be roughly grouped into two main groups: one based on probabilistic methods that use data about known seismicity in the region, and another, which is based on data related to the faulting processes and determination of seismically active faults. Both groups of methods are relatively good for seismically active regions. However, in regions of low seismic activity and slow deformations, there is neither ...

  • Distribution of major and trace elements in the Kovin lignite (Serbia)

    Dragana Životić, Olga Cvetković, Predrag Vulić, Ivan Gržetić, Vladimir Simić, Konstantin Ilijević, Biljana Dojčinović, Suzana Erić, Bogdan Radić, Sanja Stojadinović, Snežana Trifunović (2019)
    geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ...

  • Investigating distant effects of the Moesian promontory: Brittle tectonics along the western boundary of the Getic unit (East Serbia)

    Ana Mladenović, Milorad D. Antić, Branislav Trivić, Vladica Cvetković (2019)
    In this study, we report evidence for brittle deformation in a part of the Carpatho–Balkan orogen, which is explained in terms of effects of the rigid Moesian promontory of the European plate on fault kinematics in East Serbia. We focus on the westernmost part of the Getic Unit of the East Serbian Carpatho–Balkanides, i.e. the Gornjak–Ravanica Unit, located between two main thrusts that were repeatedly activated from Early Cretaceous to recent times. We combine a new data set on ...

  • Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations

    Ivana Vasiljević, Snežana Ignjatović, Branislav Sretković (2024)
    The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ...

Results of the analysis showed that entrainment material affects final results of transportation model, runout distance, deposition area and volume of debris flow. In both cases entrainment volume is very ...
