Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations
The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ...... l Sciences, 50(1): 127-139.

Ontološki model upravljanja rizikom u rudarstvu
Olivera Kitanović (2021)Rudarska proizvodnja obuhvata kompleksne tehnološke sisteme, što nameće potrebu za uspostavljanjem i unapređivanjem sistema upravljanja rizikom. Heterogenost i obim podataka neophodnih za upravljanje rizikom zahtevaju sistem koji ih na fleksibilan način integriše i omogućava njihovo optimalno korišćenje. Osnovni cilj ove disertacije je razvoj ontologije za domen rudarstva i na njoj zasnovanog modela za upravljanje rizikom. Njegova realizacija podrazumeva i implementaciju algoritama ekstrakcije informacija za popunjavanje ontologije, kao i odgovarajuće softversko rešenje.

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 ...... ‘(gold OR Au) AND (Bor OR Bor district)’. For evaluation standard measures were used, namely Precision P = tp/(tp+ fp), Recall R = tp/(tp+ fn), and F- measure F = 2 ·P ·R/(P +R), where tp – true positive is the number of relevant documents retrieved, fp – false positive is the number of non-relevant documents ...

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

INVENTS: A Hybrid Mine Ventilation Planning and Design System
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 ......

Daljinsko merenje temperature na bušotinskom cevovodu
Aleksa Petrović (2024)Ovaj diplomski rad analizira daljinsko merenje temperature na bušotinskim cevovodima, koje je od velike važnosti za kontrolu i nadzor nad industrijskim procesima posebno u ekstremnim uslovima kao što su visoke temperature i pritisci u bušotinama. Opisane su različite vrste temperaturnih senzora, kao što su termoparovi, bimetalni i otpornički termometri, kao i senzori na bazi optičkih vlakana, koji se primenjuju za kontinualno merenje temperature duž cevovoda u realnom vremenu.
