The duties of the department for designing of exploitation of mineral ores are scientific, developmental and innovation research, designing of mines with surface, drilling and underwater exploitation, the designing of surveillance and management systems and logistical engineering operations in geology, hydro-geology, dewatering of mines, geodesics, reclamation, revitalization and landscaping of degraded areas through mining.
The department for designing of the exploitation of the mineral ores is the linchpin of the Mining Institute since its founding. During the years of creation by the Mining Institute, the department was the initiator and the bearer of the primary function of research and designing integration of all segments of the Institute. Th e contributions and results of the department from this period are impossible to quantify, they number in thousands of projects, plans, studies, expertise, expert evaluations, applied research and numerous development and scientific projects realized for the necessities of the mining-ore complex of Yugoslavia and Serbia.
Through development and introduction of new approaches and methods into designing, engineering analysis and decision making, the department had spearheaded and set new, highly creative standards. The base of these results is the personnel potential i.e. the combination of experience and high expertise of the most prominent mining engineers and constant rejuvenation, education and preparation of the youth to take over the demanding research and designing assignments. In this manner the department had become a school which produced numerous leading mining experts.
Thanks to the personnel top expertise, established high standards in designing and a constant and immediate contact with problems in mines, the department has infl uenced the modernization of production processes, improvement of the existing ones, creation and introduction of new more efficient and safer technologies, environmental protection, reengineering of exploitation operations and maximization of the usage of the mineral ore basins.
The contributions of the department for deigning of exploitation of mineral ores, the development and great rise in Yugoslavian and Serbian mining in the second half of the XX century are indisputable.

There is no mining system or an important mine in Yugoslavia or Serbia in whose opening, development, reconstruction or technological modernization the department was not a part of with its project solutions on an idea or executive level.

For exploitation of energy mineral ores those are: Mining energy-industrial combine Kolubara, Industrial energy combine Kostolac, the coal basin of Kosovo, Mining energy combine Bitolj, coal mine Oslomej, Mine for underwater coal exploitation of Kovin, the coal mine Pljevlja, Mine and thermal plant Ugljevik, Mine and thermal plant Gacko, coal mine Stanari, coal mine Velenje, coal mine Trbovlje, coal mines of Istra, coal mine Kreka, coal mine Banovići, mid-Bosnian coal mines Zenica, coal mine Mostar, mines of Aleksinac, brown coal mine Bogovina, brown coal mine Vrdnik, stone coal mine Vrška Čuka, stone coal mine Dobra sreća, West-Morava coal basin, mines of Ibar, coal mine Jankova klisura, brown coal mine Jasenovac, brown coal mine Jelašnica, brown coal mine Manasija, lignite mine Lubnica, stone coal mines Podvis and Tresibaba, brown coal mine Rembas, stone coal mine Rtanj, brown coal mine Soko and brown coal mine Štavalj.

The department has produced a designing engineer work in the exploitation of metallic ores which can be viewed from the list of complex mining production systems and mines: Mining smelting basin of Bor, mining metallurgic chemical combine of Trepča (mine Trepča – Stari trg), copper mine of Majdanpek, copper mine of Bučim, mine – Rudnik, mine of Zajača, boxite mine of Klina, lead and zinc mine of Srebrenica, lead and zinc mines of Kišnica and Ajvalija (Ajvalija, Badovac, Kišnica, Novo Brdo), lead nad zinc mines of Kopaonik (Belo brdo, Crnac, Žuta prlina, Jelakce, Koporić), mine of Veliki majdan, mine of Grot, mine of Lece, mine of Podvirovi, mine of Suva ruda, mine of Sasa, lead and zinc mine of Brskovo, boxite mines of Nikšić, Boksit Milići, boxite mine of Jajce, boxite mine Klina, Feronikl Glogovac, Feni (nickel ore mine of Rzanovo) Kavadarci, iron ore mines of Omarska, open pits of iron ore Damjan and Tajmište, uranium mine of Žirovski vrh, gold mine of Ćao – Pato (Burma, today’s Myanmar) etc.
It is a wide range of projects from the department that were made for the necessities of the non-metallic mineral ore industry, foremost Magnohrom Kraljevo, the cement factory of Beočin, Cement factory of Kosjerić, cement factory Djeneral Janković, construction materials industry Toza Marković Kikinda, construction ceramics industry Polet Novi Bečej, open limestone pit Jelen do, Kopaonik Ub, quartz sand mine Rgotina, gold pit Vranjska Banja, Nemetali Topola, Venčac Arandjelovac, non-metal mines Rakovac etc.
The associates of the department have made their contributions to the mining science, engineering, industry and education through numerous master thesis and doctoral dissertations, organization of scientifi c and expert seminars, publication of over a thousand science and expert papers, dozens of monographs, textbooks and expert books. The crowning achievement of this work is the participation of the associates of the department in the preparation of the monograph “Serbian mining and geology in the second half of the XX century” (2014, Belgrade) whose co-publisher is the Mining Institute.

Today the department for designing of exploitation of mineral ores, through its integrated management system and licenses fulfi lls all modern standards i.e. the conditions to be accredited and to be of merit for its area of expertise.
