  • Effectiveness Analysis of Different Bucket-wheel Excavators

    Stevan Đenadić, Predrag Jovančić, Dragan Ignjatović, Miloš Tanasijević, Filip Miletić (2021)
    Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator. It ...

  • Петрологија црвених пешчара источне Србијe

    Андреј Марковић (2024)
    У источној Србији формација црвених пешчара има велико распрострањење и улази у састав многих планина овог дела наше земље. Формацију чине кластичне стене интензивно црвене боје псамитске, ређе псамитско-псефитске структуре и алевритске структуре. Ове стене леже трансгресивно преко старијих пермо-карбонских и карбонских стена, док навише прелазе у доњотријаске седименте. Формација црвених пешчара захвата два појаса унутар Карпато-балканида – унутрашњи и средишњи део. Узорци анализирани у овом раду део су средишњег појаса.

  • Design of a sucker rod pumping system

    Ana Ponoćko (2024)
    For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs. The first part of the paper presents the underground and surface equipment of the rod pump and describes the operation of the entire system. The ...

  • 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.

  • Self-Engineering: Possibilities for Maintenance Operations in the Mining Machines Industry

    Steven Manders, Milorad Pantelić, Vladimir Milisavljević, Alberto Martinetti (2021)
    Self-engineering is a relatively new branch of knowledge that aims to understand how systems could “autonomously” re-configure or repair themselves without the intervention of the operators. A direct field of application is within the maintenance spectrum. Having systems or machines capable of self-detecting or even self-repairing could represent a game-changer, in capital asset fields such as the mining industry in particular. This paper aims to investigate the possible benefits and challenges of self-engineering / self-maintenance concerning mining machines, specifically bucket-wheel ...

  • Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia

    Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)
    Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community. On the example of the "Valjevo" B-Li deposit, data on structural settings and previous hydrogeological investigations were combined with the results of resource drilling and geophysical ...

  • Analysis of the exhaust emissions inventory from auxiliary mining machines

    Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović (2023)
    Open-pit coal mines are equipped with a large number of mining machines and vehicles with diesel engines. Due to common daily operation of these machines and vehicles large amounts of exhaust gases which contain numerous pollutants are emitted into the atmosphere. The demand to reduce air pollution induced the activities in developed countries to map and calculate all gases emitted by industries to formulate and select adequate preventive activities. In collaboration with machine manufacturers, emission standards for off-road machines ...

  • Geomagnetna bura kategorije G5 u maju 2024. godine

    Magdalena Marčeva (2024)
    Zemlja poseduje magnetno polje, koje je generisano u njenom spoljašnjem jezgru. Magnetno polje Zemlje je konstantno izloženo dejstvu sunčevog magnetnog polja i zračenja koje se sa Sunca emituje. Naelektrisane čestice koje pristižu sa Sunca stupaju u interakciju sa magnetosferom, što dovodi do različitih geomagnetnih poremećaja.Geomagnetna aktivnost direktno je proporcionalna intenzitetu sunčevog zračenja koje dolazi do Zemlje.
