  • Hidrogeohemijska valorizacija esencijalnih mikroelemenata mineralnih voda Srbije

    Jana S. Stojković (2013-09-25)
    Mineralne vode još od davnina privlače pažnju ljudi i to kako u pogledu istraživanja iproučavanja, tako i u pogledu njihovog iskorišćavanja. Naročito je važno poznavanjesadržaja mikroelemenata u njima, jer su to komponente njihovog hemijskog sastavakoje ih odvajaju od tzv. „običnih“ malomineralizovanih voda.U ovom radu proučavani su odabrani esencijalni mikroelementi (fluor, bor, litijum,kalijum, stroncijum i silicijum), u mineralnim vodama Srbije, pri čemu je analiziranopreko 130 uzoraka mineralnih voda iz različitih geoloških sredina, to jest hidrogeološkihrejona. Cilj ovog istraživanja bio je ...

    Dragana D. Petrović (2015-12-29)
    Centralni deo Balkanskog poluostrva je geotektonski veoma složen. Tetis je zatvorentokom gornjeg mezozoika, a ofioliti na zapadu i ofioliti Vardarske zone predstavljajuostatke nekadašnjih okeanskih prostora. Najistočniji deo Vardarske zone razlikuje se odsvih ostalih ofiolita na Balkanskom poluostrvu i karakteriše se najizraženijim suprasubdukcijskimafinitetom. Istočna vardarska zona locirana je u centralom delu Srbije.Na severu se prostire do Apusena u Rumuniji, a na jugu obuhvata cetralni deoMakedonije i Peonias zonu u severnoj Grčkoj.

    Stevan Đenadić, Predrag Jovančić, Dragan Ignjatović, Filip Miletić, Ivan Janković (2019)
    Hidraulični bageri primenjuju se u različitim oblastima privrede a najzastupljeniji su u građevinarstvu i rudarstvu. Na površinskim kopovima sa kontinualnim sistemima, klasifikuju kao pomoćna mehanizacija a na površinskim kopovima sa diskontinualnim sistemima, kao osnovna mehanizacija. Kako je u oba slučaja njihova primena neizostavna, važno je izvršiti adekvatnu analizu postojećih podataka, u cilju optimizacije izbora tipa hidrauličnog bagera u odnosu na uslove rada datog površinskog kopa. U radu su opisane različite višekriterijumske metode koje su korišćene za analizu hidrauličnih bagera. ...

  • Геолошке карактеристике лежишта нафте која се експлоатишу еруптивном методом

    Милица Милићевић (2024)
    Геолошке карактеристике специфичних лежишта утичу на различите начине на ефикасност еруптивне методе. Најзначајније геолошке карактеристике које делују на еруптивну методу јесу порозност, пропусност, тип лежишта, резервоар стијене, као и тип замки. Еруптивна метода подразумјева коришћење природног притиска ради лакше експлоатације нафте и гаса из резервоара. У завршном раду су приказани различити типови лежишта и њихове геолошке карактеристике, као и предности и недостаци еруптивне методе код истих.
