  • Razvoj integralnog modela za optimizaciju diskontinualnog sistema proizvodnje na površinskim kopovima nemetala

    Miodrag Čelebić (2024)
    Izbor optimalne mehanizacije u diskontinualnom sistemu transporta je jedna od najvažnijih odluka koju treba donijeti prilikom projektovanja površinskih kopova. Pri izboru optimalne mehanizacije, uticaj ima veliki broj faktora, kako prirodnih – geoloških i ekoloških, tako i tehničkih, ekonomskih i socijanih. Neki od njih se mogu izraziti numerički, u određenim mijernim jedinicama, a neki opisno, lingvističkim varijablama, shodno uslovima koji vladaju na rudnim ležištima, a koje karakterišu visok stepen neizvjesnosti i neodređenosti kako prilikom istraživanja, tako i tokom procesa eksploatacije ...

  • Primena digitalne fotogrametrije u rudniku Rudnik

    Nikola Mirković, Luka Crnogorac, Katarina Urošević (2023)
    Digitalna fotogrametrija, lasersko skeniranje i virtuelizacija sve više pronalaze aktivne uloge u rudarstvu, prvenstveno zbog svoje široke mogućnosti primene. Laserskim skeniranjem i fotogrametrijom snimaju se i kreiraju 3D modeli otkopa, jamskih hodnika, površinskih kopova, površinskih objekata (zgrada, spomenika, predmeta), a vrši se skeniranje celih rudnika koji se rekonstruišu u 3D digitalne modele. Fotogrametrija predstavlja proces fotografisanja objekata pomoću fotoaparata i daljom obradom fotografija u različitim softverskim alatima kreiraju se realne kopije 3D modela objekata ili predmeta u digitalnoj formi.

  • Modeliranje tehnoloških procesa u rudarstvu u uslovima nedovoljnosti podataka primenom teorije grubih skupova

    Zoran M. Štirbanović (2015-07-01)
    Rudarstvo, a u okviru njega i priprema mineralnih sirovina, se odlikuje složenošću tehnoloških procesa što je posledica velikog broja uticajnih parametara. Samim tim je potrebno biti veoma obazriv prilikom donošenja odluka u oblasti rudarstva. U cilju što efikasnijeg funkcionisanja procesa, moguće je primeniti različite metode koje služe za pojednostavljenje procesa odlučivanja. Jedna od takvih metoda jeste i teorija grubih skupova. Ona predstavlja relativno novu matematičku teoriju koja je pogodna za razumevanje nepreciznih i nepotpunih podataka kao i za otkrivanje ...

  • A hundred years of Milutin Milanković's climate change theory - geological implications

    Dejan Radivojević (2020)
    Миланковићева теорија циклуса објављена пре сто година је најважнија теорија у наукама које проучавају климу и имала је велики утицај на дисциплине које се баве Земљом. Ипак, његов рад је чекао више од педесет година да би добио потврду. Може се рећи да Миланковићев рад највећи утицај на геологију има у изради астрономске временске скале, подршци хипотези континенталног дрифта и палеоклиматологији. Добри резултати примене астрономске временске скале на неогене седименте иницирали су примену ове методе у мезозојским и у последње ...
