  • 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 – ...

  • Hyperpycnites within the Devonian-Carboniferous flysch of the Carpatho-Balkanides (Kostadinovica, eastern Serbia)

    Miloš Radonjić (2020)
    This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kučaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality. The sedimentological data and the characteristics of the fossil material support the proposed model in which the sediment was at ...

  • Development and Application of Methodology for Quantification of Overbreaks in Hard Rock Tunnel Construction

    Zoran Berisavljević, Dragoljub Bajić, Vojkan Jovičić (2023)
    A methodology for determining overbreaks in hard rock tunnel construction using the drill-and-blast technique is presented in this paper. The methodology was developed for and applied to crystalline medium- to thick-bedded limestone, but it can be used in any jointed hard rock mass. Overbreaks are inevitable in hard rock tunnelling in a low-confinement environment (shallow tunnels up to several hundred meters deep) as a result of wedge failures along unfavourably oriented discontinuities caused by blasting. It is widely accepted ...

  • Integrated energy planning approach for accelerating energy transition of households

    Boban Pavlović, Marija Živković, Dejan Ivezić (2023)
    The success of energy transition planning depends on several influential and variable factors that need to be considered and tracked in modeling to support policymakers. Expert-based energy models are mainly developed following the assumptions of experts and, in most cases, a limited number of stakeholders. This top-down modeling approach will provide satisfactory results in centrally managed energy sectors (electricity generation and distribution, district heating, etc.), where further decisions could be projected relatively precisely. However, the same approach will not ...

  • An Experimental Investigation of the Environmental Risk of a Metallurgical Waste Deposit

    Jasmina Dedić , Jelena Djokic , Jovana Galjak, Gordana Milentijević, Dragan Lazarevic, Živče Šarkočević, Milena Lekić (2022)
    The aim of this study is to investigate the environmental risk of long-term metallurgical waste disposal. The investigated site was used for the open storage of lead and zinc waste materials originating from a lead smelter and refinery. Even after remediation was performed, the soil in the close vicinity of the metallurgical waste deposit was heavily loaded with heavy metals and arsenic. The pollutants were bound in various compounds in the form of sulfides, oxides, and chlorides, as well ...

  • Design of the Opencast Coal Mine Drmno Dewatering System

    Vladimir Pavlović, Dušan Polomčić, Tomislav Šubaranović (2014)
    Development of mining in the opencast mine Drmno from Kostolac basin in Serbia is carried out in the increasingly complex geological and hydro geological conditions with the decline of the coal seams to the alluvial part of Europe's largest river Danube. Greater depth and inflow of groundwater significantly increase costs for dewatering facilities construction with the requirement for optimizing of this more and more important surface mining process. Making decision on screen construction in the opencast mine with redesign ...

  • Hidrodinamički proračun zaštite površinskog kopa Drmno od podzemnih voda u periodu 2018-2022. godina

    Dušan Polomčić, Tomislav Šubaranović, Zoran Stojićević (2019)
    Površinski kop lignita Drmno nalazi se u blizini velikih reka (Dunav i Mlava), zbog čega eksploatacija otkrivke i lignita u velikoj meri zavisi od sistema zaštite od podzemnih voda. Ukoliko je sistem zaštite od podzemnih voda dobro isplaniran, a njegov kapacitet dobro proračunat, onda će se eksploatacija obavljati u suvoj sredini, što podrazumeva sigurnu proizvodnju otkrivke i lignita. U današnje vreme uz primenu adekvatnih softvera olakšano je kvalitetno planiranje i proračunavanje sistema za zaštitu površinskih kopova od podzemnih voda. ...

  • The lost freshwater goby fish fauna (Teleostei, Gobiidae) from the early Miocene of Klinci (Serbia)

    Katarina Bradić-Milinović, Harald Ahnelt, Ljupko Rundić, Werner Schwarzhans (2019)
    Freshwater gobies played an important role in the Miocene paleolakes of central and southeastern Europe. Much data have been gathered from isolated otoliths, but articulated skeletons are relatively rare. Here, we review a rich assemblage of articulated gobies with abundant otoliths in situ from the late early Miocene lake deposits of Klinci in the Valjevo freshwater lake of the Valjevo-Mionica Basin of Serbia. The fauna was originally described by Anđelković in 1978, who noted many different fishes, including one ...

  • A Fuzzy Expert Model for Availability Evaluation

    Dejan Ivezić, Miloš Tanasijević, Predrag Jovančić, Radiša Đurić (2019)
    Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The ...

  • Održivi razvoj rudarskog sektora

    Vladimir Pavlović, Dragan Ignjatović, Tomislav Šubaranović (2022)
    Imajući u vidu sve veću zabrinutost za stanje životne sredine i socioekonomsku nejednakost, sektorska održivost bez obzira na privrednu delatnost, privlači sve veću pažnju kako globalno tako i lokalno. U tom smislu postoji konsenzus kod svih zainteresovanih strana da čovečanstvo treba da usvoji mere za promenu trenutno neodrživih obrazaca proizvodnje i potrošnje. Rudarska industrija igra fundamentalnu ulogu u ovom kontekstu, privlačeći pažnju kroz različite inicijative tokom poslednjih decenija. Neke od njih su čak i primenjene u praksi ali konsenzus ...

  • Overview of the hydrogeological investigations of recently discovered world class deposits in Serbia

    Nebojša Atanacković, Vladimir Živanović, Veselin Dragišić, Sava Magazinović (2019)
    Europe industry has growing concerns on availability of the raw materials. To address this challenge, the European Commission has created a list of critical raw materials for the EU, launched EIT Raw Materials initiative, and continuously support research projects (like INTRAW, UNEXMIN etc.) with the aim of reducing the dependency and meeting growing demands. In the last 15 years Serbia is experiencing new bust in geological exploration of mineral deposits. Currently 167 exploration licenses are active, covering approximately 6000 ...
