Analiza hidrauličke veze između reke Save i podzemnih voda na izvorištu za vodosnabdevanje Obrenovca
Na izvorištu „Vić bare“ formiranom u aluvijonu Save za vodosnabdevanje Obrenovca u poslednje dve decenije izvedeno je više detaljnih hidrogeoloških istraživanja u cilju utvrđivanja rezervi podzemnih voda i izdvajanja zona sanintarne zaštite. Monitoring podzemnih voda u celoj zoni izvorišta, za potrebe izrade hidrodinamičkog modela, omogućio je i hidrauličku analizu odnosa površinskih voda reke Save i podzemnih voda na izvorištu sa kojeg se trenutno zahvata do 310 l/s vode. U radu su prikazani rezultati korelacione analize, odnosno ispitivanja na ...Dragoljub Bajić, Bojan Hajdin, Dušan Polomčić, Vesna Ristić Vakanjac.

Hydrodynamic analysis of radial collector well ageing at Belgrade well field
The origin and effect of hydraulic resistances on the rate of ageing of radial collector wells are identified through numerical hydrodynamic analysis. The research includes hydrodynamic modeling of one such well with new laterals at Belgrade well field. The performance of the laterals is aggravated by rapid ageing. The change in the hydraulic parameters of the laterals during the first decade of operation is analyzed through simulations of the groundwater regime with realistically specified geometries and hydraulics of the ...Đorđije Božović, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković.

Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija...

Analysis and visualization of geophysical well-logging data from closely spaced boreholes
Geophysical logging measurements for determining the condition of the rock mass on the dam profile and locating the predisposed directions of water circulation and loss from the reservoir were conducted in four boreholes distributed at a close distance. The survey was carried out in a typical karst terrain, which is an additional challenge for defining the geological model, especially in terms of water retention. That kind of data set provides an excellent opportunity for a new approach to analysis ...... 2024-11-04 09:12:49 Analysis and visualization of geophysical well-logging data from closely spaced boreholes Branislav Sretković, Ivana Vasiljević, Dimitry Sidorov - Biryukov Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Analysis and visualization of ...
