Contents of potentially toxic elements in residual soils of a long-term mining region: a key study from Central and Western Serbia
Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković (2022)Regional geochemical research of residual soil was conducted in an area of about 20,000 km2 in the region of Central and Western Serbia, where six metallogenetic zones and mining since ancient times have been documented. The geochemical background variation in the residual soil was established upon the contents, spatial pattern and natural background of potentially toxic elements (PTEs). The limits of natural background values (mg·kg-1) were determined by the integral method. Our data show that anomalous concentrations of As, ...Milun Jovanović, Dejan Prelević, Vidojko Jović, Danica Srećković-Batoćanin, Snežana Branković.

Hybrid Model for Optimisation of Waste Dump Design and Site Selection in Open Pit Mining
Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic (2023)Waste management is an unavoidable technological operation in the process of raw material extraction. The main characteristic of this technological operation is the handling of large quantities of waste material, which can amount to several hundred million cubic metres. At the same time, this operation must comply with all administrative and environmental standards. Therefore, optimising waste rock management (particularly haulage and dumping) has the potential to significantly improve the overall value of the project. This paper presents a hybrid ...Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic.

Non-Detonating Chemical Mixture for Non-Invasive Methods of Rock Breaking
Within the Innovation developed several different non-detonating chemical mixtures for non-invasive methods of rock breaking. Laboratory and polygon tests gave the satisfactory results and knowledge enough to start the practical experiments in the field. The basis of this innovation is a theoretical assumption that certain chemical mixtures release a large quantity of gases during combustion. If these gases are found in the enclosed space a growing pressure on the walls of the chamber in which combustion takes place will ...Lazar Kričak, Milanka Negovanović, Nikola Simić, Stefan Milanović.

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.

Indexing of textual databases based on lexical resources: A case study for Serbian
In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...... Natural language processing for online applications: Text retrieval, extraction and categorization, vol. 5. John Benjamins Publishing (2007) 5.
