  • Valorization of non-balanced coal reserves in Serbia for underground coal gasification

    David Petrović, Lazar Kričak, Milanka Negovanović, Stefan Milanović, Jovan Marković, Nikola Simić, Ljubisav Stamenić (2019)
    In the name of a better and safer energy future, it is our responsibility to focus our knowledge and activities to save on imported liquid and gas fossil fuels, as well as coal on which energy security of Serbia is based. The rationalization in the use of available energy resources certainly positively affects economy and the environment of a country. This paper indicates motivations for the application of the underground coal gasification process, as well as surface gasification for ...

  • Процјена хазарда и ризика од клизишта за различите нивое просторног планирања у Републици Српској, БиХ

    Цвјетко С. Сандић (2022)
    Територија Републике Српске је у посљедних десетак година веома угрожена активирањем нових и реактивирањем старих клизишта. Она својим дјеловањем наносе огромне материјалне штете, па и људске жртве, те је неопходно озбиљније третирање и дјеловање у борби са овим природним хазардом. Чест проблем јесте одговорност, тј. надлежност институција из ове области и недостатак у законској регулативи која готово никако или само површно обрађује област хазарда и ризика од клизишта. Усљед непостојања праксе и усвојених методологија које су у примјени у свијету, циљ ...

  • INVENTS: A Hybrid Mine Ventilation Planning and Design System

    Lilić Nikola, Stanković Ranka, Obradović Ivan (2013)
    Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper we ...
