Техно-економска оцена подземног откопавања лежишта бакра применом коморно-стубне методе
Александра Бараћ (2024)Коморно-стубна метода са блоковским откопавањем и засипавањем откопа паста засипом омогућује високу продуктивност, флексибилност при раду, остварење пројектованог производног задатка, минимално осиромашење откопане руде, у овом случају руде бакра, висок степен искоришћења расположивих рудних резерви. Припрема лежишта за експлоатацију представља инвестицију у рударској производњи,а сам коначан производ треба ,не само да отплати те трошкове, већ и да донесе новчану добит.Самим тим је од великог значаја адекватан одабир методе откопавања, која ће на најбољи могући начин испунити све захтеве.Основни показатељи ...... омска оцена подземног откопавања лежишта бакра применом коморно-стубне методе Александра Бараћ Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Техно-економска оцена подземног откопавања лежишта бакра применом коморно-стубне методе | Александра Бараћ | | 2024 ...Александра Бараћ.

The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector
Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route.

A Model for Determining Fuzzy Evaluations of Partial Indicators of Availability for High-Capacity Continuous Systems at Coal Open Pits Using a Neuro-Fuzzy Inference System
This paper presents a model for determining fuzzy evaluations of partial indicators of the availability of continuous systems at coal open pits using a neuro-fuzzy inference system. The system itself is a combination of fuzzy logic and artificial neural networks. The system availability is divided into partial indicators. By combining the fuzzy logic and artificial neural networks, a model is obtained that has the ability to learn and uses expert judgment for that learning.

Adsorption and degradation of some psychiatric drugs by sol-gel synthesized titania-based photocatalysts: influence of tungsten and sodium content

Krstić, Aleksandar Kremenović, Tatjana Srećković, Aleksandar Golubović (2019)Mesoporous anatase nanopowders were doped with 0.05−0.5 mol% of W6, in order to obtain more efficient photocatalyst than TiO2 Degussa P25 in the degradation of amitriptyline (AMI) under simulated solar irradiation (SSI). Dominant XRPD peaks were ascribed to anatase phase, with additional peaks which could correspond to brookite, TiO2 bronze and sodium titanate, Na2Ti9O19. The Raman scattering measurements have confirmed anatase as dominant phase, with broad Raman feature at ~270 cm−1 possibly related to Ti–O–Na stretching vibration.

Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age.

Stepen drobljenja stena ima veliki uticaj na efikasnost daljih operacija utovara, transporta, drobljenja i mlevenja. Optimalno drobljenje stena pri proizvodnom miniranju utiče na smanjenje ukupnih troškova proizvodnje. Stoga je pouzdana procena veličine drobljenja odminirane stenske mase veoma važno pitanje, ne samo u operacijama miniranja, već i u rudarskoj proizvodnji.
