  • Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series

    Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)
    Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...

  • Palaeoflora of Kamenica (Pranjani Basin, western Serbia)

    Zorica Lazarević, Ljubica Milovanović, Jelena Milivojević, Ivana Vasiljević (2019)
    Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoas sociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleo gene phytoassociations.The palaeoflora from Kamenica is characterized with leaf imprints larger than in other ...

  • Vodosnabdevanje i održivo upravljanje podzemnim vodnim resursima u Srbiji

    Dušan Polomčić, Zoran Stevanović, Dragoljub Bajić, Bojan Hajdin, Vesna Ristić-Vakanjac, Petar Dokmanović, Saša Milanović (2012)
    Slično većini evropskih zemalja, udeo podzemnih voda u javnom vodosnabdevanju u Srbiji je oko 75%. Najveće rezerve su akumulirane u vodonosnim naslagama intergranularne poroznosti neogene i kvartarne starosti, kao i u karstnim izdanima. One su jedini izvor vodosnabdevanja pijacom vodom za Vojvodinu i veći deo Srbije. Delovi sa malim rezervama podzemnih voda su Šumadija i južni delovi zemlje, gde se koriste u većoj meri površinske vode. Do sada izvedena hidrogeološka istraživanja pokazuju da se zahvata oko 30% obnovljivih rezervi ...

    Dragana Đurić, Katarina Bogićević, Draženko Nenadić, Mihajlo Jovanović, Aleksandra Savković (2023)
    Fosilna fauna pleistocenskih pećina odslikava sastav faune njihove okoline. Najčešće se u njima naleze ostaci krupnih sisara ledenog doba koji su je koristili kao stanište. Uz njih česti su i ostaci drugih sitnih kičmenjaka kao što su sitni sisari, ribe, vodozemci, gmizavci i ptice. Ostaci sitnih kičmenjaka u većini slučajeva u pećinu dospevaju kao plen grabljivica (ptice i sisari) ali je manji broj njih pećinu koristio i kao sklonište ili stanište.

  • 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.

  • 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). ...

  • Overwiew of In-Pit Crushing & Conveying Technology in Open Pit Mines

    Ali Nasirinezhad, Dejan Stevanović, Dragan Ignjatović, Petar Marković (2021)
    The conditions under which contemporary surface mining operations is carried out obviously becoming increasingly complex. In such complex conditions, the optimization of haulage systems as the technological phase with the largest share in the total operating costs, is very important from the aspect of achieving profitability of the mining project. In a large number of cases, the application of traditional haulage systems with trucks (as the most dominant type of haulage in open pit mines) does not lead to ...

  • Quantitative landslide risk assessment in the city of Tuzla

    Miloš Marjanović, Biljana Abolmasov, Cvjetko Sandić, Miralem Mulać, Petar Begović (2021)
    In the climate-changing conditions, geological environment interacts more dramatically with the urban fabric than before. The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends. In effect, many processes which can be triggered by either side, nature or engineering, are becoming more pervasive than before, and such is the case with landslides. Dealing and managing landslides requires few crucial steps, starting from collecting data on landslide location and typology – ...

  • Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae

    Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using NMRspectroscopy as cis- and trans-dehydroicetexane. Both have a 9(10?20)-abeo-abietane or icetexane skeleton, consisting of a 6-7-6 tricyclic framework with seven carbons in ring B instead of the usual six in common diterpanes of the abietane-type. Dehydroicetexanes can be detected using GC-MS-MS in m/z 270?146 chromatograms without interference from dehydroabietane or other isomers. Dehydroicetexanes are often abundant ...
