Wells calculation for the protection of opencast mine Radljevo North from groundwater
Za projektovanje kvalitetnog sistema zaštite jednog površinskog kopa od podzemnih voda bitno je da ulazni podaci budu verodostojni, kako bi se na osnovu njih izvršili potrebni proračuni objekata odvodnjavanja podzemnih voda. Proračunima za površinski kop Radljevo Sever je omogućeno da se dobije potreban broj bunara kako bi oni pravilno funkcionisali i obezbedili potrebno obaranje podzenih voda.Dušan Polomčić, Vladimir Petković, Miloš Jeremić.

Hidrodinamički proračun zaštite površinskog kopa Drmno od podzemnih voda u periodu 2018-2022. godina
Površinski kop lignita Drmno nalazi se u blizini velikih reka (Dunav i Mlava), zbog čega eksploatacija otkrivke i lignita u velikoj meri zavisi od sistema zaštite od podzemnih voda. Ukoliko je sistem zaštite od podzemnih voda dobro isplaniran, a njegov kapacitet dobro proračunat, onda će se eksploatacija obavljati u suvoj sredini, što podrazumeva sigurnu proizvodnju otkrivke i lignita. U današnje vreme uz primenu adekvatnih softvera olakšano je kvalitetno planiranje i proračunavanje sistema za zaštitu površinskih kopova od podzemnih voda. ...Dušan Polomčić, Tomislav Šubaranović, Zoran Stojićević.

Ocena zaštitne funkcije povlatnih slojeva izvorišta Jasik (Opština Batočina) primenom GLA metode
U cilju utvrđivanja rezervi podzemnih voda i analize uslova zaštite u periodu 2012. i 2013. godine, sprovedena su detaljna hidrogeološka istraživanja na području izvorišta Jasik (opština Batočina). Uspostavljen je sistem monitoringa, čiji je rezultat predstavljao prikupljanje detaljnih hidrogeoloških podataka. Za potrebe analize, izrađen je hidrodinamički model, na osnovu koga je simulirano kretanje podzemnih voda, odnosno, utvrđene zone sanitarne zaštite. Pored navedenog, za potrebe utvrđivanja uslova zaštite podzemnih voda, bilo je neophodno utvrditi podložnost aluvijalne izdani izvorišta Jasik zagađenju.

Tehno-ekonomska analiza varijanti sistema odvodnjavanja površinskog kopa Drmno od podzemnih voda do kraja eksploatacije
Odvodnjavanje površinskog kopa Drmno od podzemnih voda je jedan od najznačajnijih podsistema u procesu eksploatacije u veoma zavodnjenoj radnoj sredini Kostolačkog basena uglja. Već od 2006. godine, Inovirani dugoročni program razvoja eksploatacije uglja predviđa izradu ekrana, pored zadržavanja postojećih standardnih metoda odvodnjavanja od podzemnih voda linijama bunara. Iako je kasnijim Glavnim rudarskim projektom, takođe, bila predviđena izrada ekrana, njegova realizacija nije započela. Na osnovu realnog sagledavanja postojeće projektne dokumentacije, početak izrade ekrana se predviđa od 2023. godine. ...Tomislav Šubaranović, Dušan Polomčić, Vladimir Pavlović.

Design of the Opencast Coal Mine Drmno Dewatering System
Development of mining in the opencast mine Drmno from Kostolac basin in Serbia is carried out in the increasingly complex geological and hydro geological conditions with the decline of the coal seams to the alluvial part of Europe's largest river Danube. Greater depth and inflow of groundwater significantly increase costs for dewatering facilities construction with the requirement for optimizing of this more and more important surface mining process. Making decision on screen construction in the opencast mine with redesign ...dewatering system, groundwater, hydrodynamic model, dewatering wells, screen, reliability, environmental effects.Vladimir Pavlović, Dušan Polomčić, Tomislav Šubaranović.

Analiza sistema odvodnjavanja površinskog kopa Drmno od podzemnih voda sa severnim savršenim ekranom
Izrada nesavršenog ekrana do drugog sloja uglja na površinskom kopu Drmno, pored zadržavanja postojećih standardnih metoda odvodnjavanja od podzemnih voda linijama bunara, predviđena je poslednje decenije u celokupnoj rudarskoj projektnoj dokumentaciji. Iz objektivnih i subjektivnih razloga njegova realizacija nije ostvarena do danas. U međuvremenu je, uz dodatna geološka istraživanja i promenu dinamike i parametara sistema površinske eksploatacije, došlo do određenih značajnih prostornih promena geoloških i rudarskih uslova u eksploatacionom polju.

Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia
Dragoljub Bajić, Dušan Polomčić (2014)A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...groundwater lowering, groundwater management scenario, fuzzy analytic hierarchy process,expert knowledge, triangular fuzzy numbers, linguistic variables...

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.
