The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers
One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance. More than 100 bulldozers have been hired ...... of Serbia. |Тће је cycle of these machihes is 5–10 years, 50 И is hecessary 10 replace тће complete equipmeht several times тт the lifetime ој the mine.

Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations. The paper presents the basic characteristics and development of the hydrodynamic model of the open pit mine “Drmno” for 25 years. This open pit ...Dušan Polomčić, Jelena Ratković, Vesan Ristić Vakanjac.

Modeliranje i simulacija energetske tranzicije u sektoru domaćinstava
Boban S. Pavlović (2022)Aktuelnu energetsku tranziciju odlikuje ubrzanje procesa dekarbonizacije energetskih sistema, unapređenje energetske efikasnosti, razvoj čistijih tehnologija baziranih na obnovljivim izvorima energije i održivije korišćenje prirodnih resursa. Da bi se napravio ovako krupan zaokret u postojećim energetskim sistemima, osim promene postojećih tehnologija, potrebno je u planiranje energetske tranzicije uključiti i političke, sociološke, ekonomske i ekološke aspekte, a pre svega obrasce ponašanja i donošenja odluka krajnjih potrošača.

Conversion of land areas after coal mine closure and reclamation
Otkopavanje uglja površinski i podzemno praćeno je degradacijom zemljišta, promenom formiranja predela i izmenom flore i faune. Od velikog značaja je razvoj novih naučno utemeljenih pristupa obnovljanje antropogeno poremećenih predela zasnovanih na formiranju rekultivacionih i rudarskih tehnologija. Apsolutno je neophodno obezbediti sveobuhvatno kvalitetno očuvanje zemljišnih i vodnih resursa i odrediti rekultivisano zemljište za novu namenu. U ovom članku je dat pregled najpopularnijih metoda rekultivacije zemljišta i mogućnosti rekultivacije zemljišta nakon završetka rekultivacije i zatvaranja rudnika uglja.... through simple procedures. It is important to point out that the defined model can be used in all planning and exploitation phases of an open pit mine, regardless of whether it is a new mine or an open mine where exploitation is carried out.

Razvoj rudarstva i metalurgije olova i cinka u rudniku ,,Trepča’’ – Stari Trg
Posle seobe Srba 1690. i 1735. godine, dolazi do prestanka eksploatacije rudnika na prostoru sadašnje Srbije i nakon zastoja od blizu 200 godina, aktivirana je rudarsko-metalurška delatnost u Srbiji u drugom kvartalu 20. veka. Prve koncesije otkupili su Englezi 1926. godine, zatim se aktiviraju rudnici u Starom Trgu (1927.), Kišnici (1927.), Ajvaliji (1930.), Novom Brdu (1933.), a u Zvečanu počinje da radi Flotacija (1930.) i Topionica sa Rafinerijom olova (1939.).
