  • INVENTS: A Hybrid Mine Ventilation Planning and Design System

    Lilić Nikola, Stanković Ranka, Obradović Ivan (2013)
    Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper we ...

  • Optimizacija ugla nagiba generalne kosine unutrašnjeg odlagališta površinskog kopa Tamnava-Zapad

    Natalija Pavlović, Branko Petrović, Tomislav Šubaranović, Ivan Janković (2022)
    Formiranje geomehanički tabilnih unutrašnjih odlagališta otkrivke ima izuzetno značajnu ulogu pri projektovanju i planiranju razvoja površinskih kopova uglja sa aspekta preraspodele masa otkrivke, dinamike eksploatacije, ekoloških zahteva, rudarskih rizika i troškova. Uvećanje zavodnjenosti unutrašnjeg odlagališta otkrivke površinskog kopa Tamnava-Zapadno Polje, kao posledica globalnih klimatskih promena sa pojavom katastrofalnih obimnih padavina i velike poplave, dovelo je i do značajnih ali i trajnih promena geomehaničkih karakteristika materijala, umanjenja stabilnosti generalne kosine unutrašnjeg odlagališta i znatnog povećanja rudarskog rizika.

  • Environmental flows and demands for sustainable water use in protected karst areas of the Western Balkans

    Zoran Stevanović, Aleksandra Maran Stevanović, Želimir Pekaš, Romeo Eftimi, Veljko Marinović (2021)
    Karst terrains cover some 30% of the Western Balkans, where rich karst aquifers represent the main source of potable water supply and ensure the development of local economies and tourism. In this “classical karst” region, there are also numerous sites or areas under different forms of protection—from those that are included in the UNESCO World Heritage list to natural monuments and landscapes that are protected by national legislation. In and around them are specific representatives of flora and fauna ...

  • 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 ...

  • Uticaj voda Dunava na formiranje kvaliteta podzemnih voda u zoni Apatina

    Bojan Hajdin, Željko Kljajić, Vesna Ristić-Vakanjac, Milojko Lazić, Marina Čokorilo-Ilić (2018)
    Područje Apatina u proteklom periodu često je pominjano u razvojnim vodoprivrednim strategijama kao potencijalno perspektivna lokacija za izgradnju izvorišta duž obale Dunava, koje bi moglo da ima regionalni značaj. Ovim rešenjem trebao bi se prevazići problem lošeg kvaliteta vode za piće na celom području severne Bačke, tako što bi se kvalitet podzemne vode poboljšao zahvatanjem infiltriranih rečnih voda u priobalju Dunava.

  • Optimizacija faznog razvoja Površinskog kopa Ciganuša – Škorac u cilju definisanja dugoročne dinamike eksploatcije

    Dejan Stevanović, Petar Marković, Mirjana Banković, Milan Živković (2022)
    Definisanje dugoročne dinamike razvoja rudarskih radova koja je u potpunosti usaglašena sa strateškim ciljevima Investitora, veoma je zahtevan zadatak, koji vrlo često podrazumeva veliki broj ograničenja. Adekvatno definisana dinamika razvoja rudarskih radova treba da obezbedi dugoročne zahteve u pogledu kapaciteta, kvaliteta i raspodele resursa neophodnih za ispunjavanje strateških ciljeva, koji se po pravilu svode na ostvarenje maksimalnog profita. Uspešno definisanje dinamike eksploatacije (posebno kod metaličnih ležišta) u najvećoj meri zavisi od optimizacije faznog razvoja površinskog kopa, odnosno od pravilnog ...

  • Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs

    John Nyame (2024)
    The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...
