Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)
Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods.

Modeliranje tehnoloških procesa u rudarstvu u uslovima nedovoljnosti podataka primenom teorije grubih skupova
Zoran M. Štirbanović (2015-07-01)Rudarstvo, a u okviru njega i priprema mineralnih sirovina, se odlikuje složenošću tehnoloških procesa što je posledica velikog broja uticajnih parametara. Samim tim je potrebno biti veoma obazriv prilikom donošenja odluka u oblasti rudarstva. U cilju što efikasnijeg funkcionisanja procesa, moguće je primeniti različite metode koje služe za pojednostavljenje procesa odlučivanja. Jedna od takvih metoda jeste i teorija grubih skupova.

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.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry.

Hidrodinamička analiza procesa starenja bunara sa horzontalnim drenovima na beogradskom izvorištu podzemnih voda
Đorđije M. Božović (2023)Predmet istraživanja doktorske disertacije su bunari sa horizontalnim drenovima beogradskog izvorišta podzemnih voda, drugog najvećeg izvorišta ovog tipa na svetu, čiji je režim rada opterećen procesima intenzivnog starenja prisutnog od samog početka formiranja izvorišta, početkom 1950‒ih godina. Istraživanja sprovedena u okviru izrade disertacije su imala za cilj definisanje nove metodologije izučavanja procesa mehaničkog i biohemijskog kolmiranja drenova izradom detaljnih 3D numeričkih hidrodinamičkih modela, upotrebom postojećih, dostupnih i široko rasprostranjenih računarskih programa. Istraživanja su realizovana simulacijom ostvarenog režima podzemnih voda ...modeliranje podzemnih voda, hidrauličke karakteristike drenova, koeficijent propusnosti drenova, prifilterska zona drena, hidraulički otpori na drenovima, kolmiranje drenova, ulazne brzine podzemnih voda, MODFLOW, CLN Package... 193 Siergieiev, D., Ehlert, L., Reimann, T., Lundberg, A., Liedl, R., 2015.
