Hidrogeoekološki aspekti aksploatacije uglja u Pelagonijskom basenu (Makedonija)
Kostadin J. Jovanov (2016-06-24)Leţišta uglja „Suvodol“, „Brod-Gneotino“ su u eksploataciji, a leţište uglja „Ţivojno“je u fazi pripremi. Nalaze se u krajnjem jugoistočnom i juţnom delu Pelagonijskekotline. Sva tri leţišta stvorena su u neogenim sedimentima u jezerskim uslovimasedimentacije u zoni kontakta sa prekambrijumskim kristalastim stenama. Kod sva trileţišta ugalja se javljaju više slojeva različite debljine, u okviru kojih se nalaze klastičnisedimenti (gline, peskovi i dr.). U podini ugljenog basena nalaze se kristalaste steneprekambrijumske starosti.Teren u okolini leţišta uglja karakteriše se umereno kontinentalnom klimom, ...ugalj, podzemne vode, površinske vode, neogeni kompleks, izdani,transmisibilnost, nivo podzemne vode, sniţenje nivoa... izmeĎu nivoa podzemnih voda krovinske i meĎuslojne izdani ukazuju na veze koje su jako promenljive i to: r=0,79 (veoma čvrsta veza), r=0,67 (relativno čvrsta veza), r=0,43 i r=0,19 (slaba veza) do r=0,07 (nepostojanje korelacione veze).

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 ...
... negative is the number of relevant documents that were not retrieved. During the evaluation ranked responses were offered to users, and the measures P and R were calculated for sets containing the first i choices of- fered, where i ∈ [1, 120] [8]. In this way, curves showing the dependency between precision ...

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 ......
