The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ...... trg 12–16, 11000 Belgrade, Serbia 4 Kovin coal mine, Cara Lazara 85, 26220 Kovin, Serbia doi: 10.4154/gc.2019.06 Abstract A geochemical and mineralogical study was performed on lignite samples from the Upper Mio- cene Kovin deposit, hosting three coal seams.

Primena digitalne fotogrametrije u rudniku Rudnik
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.

Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements
The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...Filip Miletić, Predrag D.

Развој хибридног модела за оптиматизацију завршне контуре одлагалишта у површинској експлоатацији лежишта минералних сировина
Aлександар Додеровић (2024)Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити. Традиционални приступ избора локације и дизајна одлагалишта се карактерише парцијалним приступом, заснованом на анализи неколико водећих критеријума као и на личном искуству инжењера, често занемарујући синергетски ефекат осталих утицајних фактора Технолошке операције које се односе на манипулацију јаловином, међу којима предњачи транспорт, генеришу највећи дио трошкова у површинској експлоатацији. Такође, цјелокупан процес експлоатације додатно је ограничен ...оптимизације завршне контуре одлагалишта, хибридни модел, површинска експлоатација, генетски алгоритамAлександар Додеровић.

Оптимизација управљања процесима рекултивације површинских копова угља
Bojan S. Dimitrijević (2014-05-30)Ширење површинске експлоатације минералних сировина а нарочито енергетских ресурсафосилних горива, чине површинске копове угља просторно доминантним објектима великих рударскихбасена како у нас тако и у свету. Експлоатациона активност, прати негативне еколошке утицаје наживотну средину шире околине, што нас обавезује на интегрално планирање, ревитализацију,рекултивацију и уређење нарушеног простора за његово поновно хумано коришћење упостексплоатационом периоду. Постексплоатационо санирање и уређење предела површинских коповаи одлагалишта односно нарушеног простора изазваног рударским радовима и пратећих објеката,представља синтетички мултидисциплинарно-интердисциплинаран веома комплексан вишефазниинжењерски пројектни задатак.У уводном ...рекултивација, постексплоатациони предео, површински коп угља,вишеатрибутна анализа, одлучивање, процеси, рекултивационо решење... performed in three subject in our country and the region: 1.
