Analysis and Calculation of MMRS and Primary Gas Distribution Network in Urban Environment – Case Study Kučevo
Aleksandar Madžarević, Pavle Janković (2022)Oblast primene prirodnog gasa je veoma široka. Kao energent može se koristiti za proizvodnju energije u elektranama, toplanama i postrojenjima za kombinovanu proizvodnju energije ili za zadovoljavanje različitih toplotnih potreba u industriji i širokoj potrošnji. Gas se može upotrebiti i kao sirovina u hemijskoj i petrohemijskoj industriji, a tokom poslednjih decenija nalazi primenu i u saobraćaju kao pogonsko gorivo u SUS motorima. Sa ekološkog stanovišta, prirodni gas predstavlja najprihvatljiviji izvor energije u poređenju sa drugim fosilnim gorivima. Pri sagorevanju ...Aleksandar Madžarević, Pavle Janković.

Примена дискретног ауторегресивно – кросрегресивног модела покретног просека за прогнозу дневних вредности издашности врела Мокра и Дивљана
Бранислав Петровић, Вељко Мариновић (2021)Аутокорелациона и кроскорелациона анализа временских серија падавина и истицања подземних вода карстних врела Мокра и Дивљана (Сува планина, ЈИ Србија) извршена је ради формирања стохастичког ауторегресивно-кросрегресивног модела (ARCR) и прогнозе дневних вредности издашности. Будући да је тешко предвидети просторну дистрибуцију подземних вода у оквиру карстног хидрогеолошког система услед постојања хетерогености и анизотропности карстне издани (тј. кречњачких стена у овом случају), апликативност детерминистичких модела је минимизирана, па је примена стохастичког модела у овом случају учинковитија.

Analysis of the Influence of Burden Deviation from the Designed One on the Intensity of the Blast Vibration
Stefan Milanović, Lazar Kričak, Milanka Negovanović, Nikola Simić, Jovan Marković, Nikola Đokić (2023)This paper presents an analysis of the influence of burden deviation from the designed one on the intensity of blasting vibrations through the use of laboratory and field examinations. By definition, the burden represents the shortest distance from the axis of an explosive column charge to the free surface. It should be measured along the entire hole length, although, in practice, it is often measured only on the bench surface as the shortest distance from the axis of the ...Stefan Milanović, Lazar Kričak, Milanka Negovanović, Nikola Simić, Jovan Marković, Nikola Đokić.

A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice
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 ...... practice and specific empirical relations defined. After the input data for planning and design of the entire ventilation system have been analyzed and checked in detail, INVENTS offers a number of possibil- ities for the analysis of mine ventilation networks with the help of its ventilation simulation ...
