  • Industrija 4.0 - koncept prediktivnog održavanja 4.0 (PdM 4.0) u rudarstvu

    Predrag Jovančić, Vesna Damnjanović, Dragan Ignjatović, Miloš Tanasijević, Stevan Đenadić (2019)
    Četvrtu industrijsku revoluciju – Industriju 4.0 karakteriše upotreba cyber-fizičkih sistema. Da bi se postigla optimalna strategija održavanja (ali i eksploatacije), neophodno je razviti sisteme koji podržavaju napredne inteligentne sisteme održavanja ili tehnologije pametnog održavanja. Iz toga su proizašli postulati Prediktivnog održavanja 4.0 (PdM 4.0) koji definišu veoma blisku budućnost u oblasti održavanja tehničkih sistema pa i rudarske opreme. PdM 4.0 uključuje iskorišćenje snage veštačke inteligencije za stvaranje stalnog uvida u otkrivanje uzroka i anomalija u radu opreme, koje se ...

  • Pokazatelji recentne tektonske aktivnosti u speleološkim objektima Dževrinske grede (istočna Srbija)

    Ana Mladenović, Jelena Ćalić (2022)
    Sistem Timočkog raseda predstavljen je sistemom desnih transkurentnih raseda generalnog pružanja sever – jug, koji su bili aktivni u periodu oligocena i miocena u okviru Karpato-balkanskog orogena. Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km. Usled kompleksnih tektonskih rotacija, rasedi ovog sistema doveli su ...

  • Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation

    Maja Franković, Nevenka Novaković, Vesna Matović (2015)
    The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ...

  • Model za optimizaciju graničnog saržaja metala u rudi u funkciji dugoročnog planiranja površinskih kopova

    Daniel P. Kržanović (2016-06-14)
    Optimizacija graničnog sadržaja metala u rudi jedan je od osnovnih koraka u planiranju i dizajniranju površinskih kopova i ima za cilj postizanje maksimalne neto sadašnje vrednosti (NPV). Iz tog razloga, optimizacija graničnog sadržaja i danas je predmet mnogih istraživanja u rudarskoj nauci, sa ciljem rešavanja praktičnih problema u eksploataciji ležišta.Dugoročno planiranje eksploatacije na površinskim kopovima podrazumeva sagledavanje svih relevantih parametara i faktora (geologije rudnog ležišta, tehnologije proizvodnog procesa, kapaciteta otkopavanja i prerade, troškova, cena metala, iskorišćenja i dr) kako ...
