Definisanje specifičnih uslova dreniranja podzemnih voda na karstnim vrelima Krupac 1 i 2
Kristina Gavrilović (2024)Izvorište Krupac se nalazi u jugoistočnom delu Srbije, u blizini grada Pirota i deo je sistema za vodosnabdevanje grada i okolnih mesta. Vrela Krupac 1 i Krupac 2 su gravitaciona karstna vrela, locirana na kontaktu jursko-krednog kompleksa stena sa neogenim naslagama Pirotske kotline, čije su specifičnosti uslova dreniranja, kao i uslova cirkulacije, ispitane hidrohemijskim i izotopskim metodama, kao i opitom obeležavanja ponora Golema dubka. Ustanovljeno je da se radi o mladim vodama i sistemu bez duboke cirkulacije podzemnih voda, ...... nHcCTpHOynujy H jaBHo caormrraBatbe JIeza, H upepajie, ako ce HaBeJle HMe ayTopa Ha HaunH ojJnIpeljeH ojt crpaHe ayTopa H JnaBaorma JIHILČHIIC, daK H y KOMepIHJajiHe cBpxe.

Optimizacija površinskog kopa Ciganuša – Škorac
Vasilije Zejak (2024)U radu se govori o značaju optimizacije u savremenom rudarstvu i kako nam to softveri štede vreme, novac i olakšavaju procese planiranja.Konkretno u izradi ovog rada korišćen je softverski paket Whittle.Da bi se optimizacije mogla uspešno sprovesti, potrebno je konstruisati pre svega blok model ležišta kao i definisati niz tehno – ekonomskih parametara. Na osnovu tih podataka definiše se optimalna kontura i dinamika razvoja radova. U skladu sa definisanim podaci i odgovarajućim podlogama definisana je optimalna kontura površinskog kopa Ciganuša ...optimizacija, površinski kop Ciganuša - Škorac, blok model, strateško planiranje, optimalna kontura, dinamika razvoja, fazni razvoj...

Hyperpycnites within the Devonian-Carboniferous flysch of the Carpatho-Balkanides (Kostadinovica, eastern Serbia)
Miloš Radonjić (2020)This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kučaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality. The sedimentological data and the characteristics of the fossil material support the proposed model in which the sediment was at ...Mississippian flora, Dictyodora liebeana (GEINITZ), hyperpycnites, Kučaj-Zvonce flysch, Carpatho-Balkanides...

Proučavanje razvića Bihaćkog i Cazinskog basena primenom gravimetrijskih podataka
Bihaćki i Cazinski baseni su neogeni baseni, koji pripadaju spoljašnjim Dinaridima i formirani su tokom kasne faze razvoja Dinarida. Ovi baseni su od posebnog interesa zbog svoje geološke prošlosti i potencijalnih strukturnih karakteristika. U istraživanju, primenjeni su gravimetrijski podaci u clju boljeg razumevanja evolucije ovih basena. Primenom različitih postupaka matematičkih transformacija na gravimetrijskim podacima može se ustanoviti gravitacioni uticaj neogenih basena male gustine i mogu se detektovati strukture, koje su potencijalno vezane za njihovo formiranje.

During the highpressure and high-temperature synthesis (HPS) process at 4 GPa and 1,200 °C, sphene undergoes into phase transition, from room-temperature phase P21/a to high-temperature phase A2/a. Evidence of that structural phase transition is given in this paper using infrared, Raman spectroscopy and X-ray powder diffraction.

Da bi se ovo uskladili neophodno je imati bar jednu akumulacionu, bolje reći, izravnavajuću deponiju ...

A Model for Determining the Dependability of Continuous Subsystems in Coal Mines Using the Fuzzy Logic Approach
Nikola Stanić, Miljan Gomilanović, Petar Marković, Daniel Krzanović, Aleksandar Doderović, Saša Stepanović (2024)This study presents a unique model for assessing the dependability of continuous parts of combined systems in open-pit mining through the application of fuzzy logic. Continuous sub-systems as part of the combined system of coal exploitation in surface mines have the basic function of ensuring safe operation, high capacity with high reliability, and low costs. These subsystems are usually part of the thermal power plant’s coal supply system and ensure stable fuel supply. The model integrates various independent partial ...fuzzy logic, max-min composition, continuous part of combined system (CCS), open pit, mining, dependabilityNikola Stanić, Miljan Gomilanović, Petar Marković, Daniel Krzanović, Aleksandar Doderović, Saša Stepanović.

Design of a sucker rod pumping system
Ana Ponoćko (2024)For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs. The first part of the paper presents the underground and surface equipment of the rod pump and describes the operation of the entire system. The ......
