Analiza geomehaničke stabilnosti kosina na odlagalištima i površinskom kopu Ćeramide
Kako bi se nastavila eksploatacija dacita na površinskom kopu Ćeramide kod Rudnika, potrebno je izraditi novu projektnu dokumentaciju na osnovu novih overenih rezervi. Da bi se eksploatacija jalovine i dacita odvijala sigurno bez klizanja i obrušavanja stenskog materijala, neophodno je izvršiti proveru stabilnosti projektovanih kosina i na odlagalištima i na samom površinskom kopu. U ovom radu je upravo data analiza geomehaničke stabilnosti kosina na odlagalištima i površinskom kopu dacite Ćeramide kod Rudnika.Tomislav Šubaranović, Vladimir Čebašek, Bojan Dimitrijević, Veljko Rupar.

Double traveling valve increases rod-pump efficiency
Traditional sucker rod pumps (SRP) use a single traveling valve, but recent double traveling valve innovations have improved SRP performance and efficiency in field applications with double traveling valves installed in pumps with top mechanical seating. The valves sealed better and produced similar fluid volumes compared with the previous single-valve pumps. They also enabled a reduction in pump diameter and optimized usage of surface equipment. Overall, the double travel valve SRPs produced stable production rates and annual production targets.Miloš Petrović, Bojan Martinović, Milica Ješić, Miroslav Crnogorac.

Petrološke karakteristike dunavskog šljunka (Beograd – Zemun)
Miloš Mihajlović (2024)Dunavski šljunak u okolini Zemuna karakterističan je za obalne rečne naslage formirane dugotrajnim procesima erozije i transporta materijala koje reka Dunav nosi sa različitih područja uzvodno. Ispitivanja šljunka sa lokacije „Gemax” su pokazala je šljunak uglavnom zaobljen, najčešće u rasponu od nekoliko milimetara do nekoliko centimetara u prečniku. Kako Dunav nosi materijal sa velikog sliva, ovaj šljunak sadrži raznovrsne sastojke sa dominacijom kvarca i odlomaka stena visokosilicijskog sastava. Mineraloško-petrografska ispitivanja pokazala su prisustvo klasta različitog sastava, čime je potvrđena ...... profesor, mentor Rudarsko-geološki fakultet, Beograd 2.

Analiza hidrauličke veze između reke Save i podzemnih voda na izvorištu za vodosnabdevanje Obrenovca
Na izvorištu „Vić bare“ formiranom u aluvijonu Save za vodosnabdevanje Obrenovca u poslednje dve decenije izvedeno je više detaljnih hidrogeoloških istraživanja u cilju utvrđivanja rezervi podzemnih voda i izdvajanja zona sanintarne zaštite. Monitoring podzemnih voda u celoj zoni izvorišta, za potrebe izrade hidrodinamičkog modela, omogućio je i hidrauličku analizu odnosa površinskih voda reke Save i podzemnih voda na izvorištu sa kojeg se trenutno zahvata do 310 l/s vode.

Dynamic and Static Elastic Properties - Laboratory Investigations of Metamorphites of the "Vranjska Banja" Series
Metamorphites of the series “Vranjska banja” built predominantly of high crystallinity schist series, alternately layered double mica, gneiss, leptonite and micaschist. For the construction of the “Prvonek” dam were carried out laboratory investigations of dynamic and static elastic properties on micashist and gneiss samples in the perpendicular and parallel direction to the foliation. These investigations provided monitoring of the rock mass anisotropy properties and greater reliability of the design parameteres. As the design of mining and construction facilities becomes ...Jelena Majstorović, Bojan Dimitrijević, Suzana Lutovac, Snežana Savković, Miloš Gligorić.
