Using of explosives in modern mining is very important for the good, efficient and rational organization for obtaining of solid minerals, especially in the exploitation of mineral resources on mines with large capacities. Technological phases of drilling and blasting in the exploitation process are very important in this case, and the analysis in t...

Particulate matter (PM) is hazardous to human health. This paper deals with PM concentrations in ambient and indoor air on three locations (two being in the central parts of the city and another onenear industrial zone of the settlement of Lazarevac, lying in the outskirts of Belgrade). The aim of the paper is to assess the scope of exposure to par...

Before the electronic distance meters appears the angles measuring dominated in geodetic networks. Development of distance measuring technology and appearance of automated total stations almost equaled the efficiency of measuring angles and distances. This fact allows designer of geodetic networks to combine angles and distances in order to achieve...

During the past two decades, rapid advances in information technology have improved the accuracy and capabilities of optimization techniques. Unfortunately, great number of optimization methods in civil engineering has not found implementation in practice, mainly because the problems were treated only from mathematical point of view, disregarding a...

This paper presents one approach for the analysis of snap behaviour of simply supported elastic shallow shells. Structure is discretized with the finite strip method. Displacement field is approximated with series of products of polynomials and harmonic functions. Only geometric nonlinearity of von Karman type is considered. Equilibrium equations a...

Field research for the purpose of the construction of the Thermal Power Plant Ugljevik 3 wasconducted in two phases. In the first phase for the smaller scope of the fieldworks, more laboratory analyses were performed. In the second phase, fieldworks were conducted in a larger scaleand laboratory analyses were considerably smaller.Designers dictated...

Energetska kriza često prisutna u različitim oblicima, stvara prostora za korištenje „manje značajnih“  vidova energije. Jedan od tih vidova energije je geotermalna energija, koja se može koristiti u mjestu njenog postojanja, za različite energetske svrhe. Veoma je prihvatljiva i najčešće povoljnije cijene u odnosu na komercijalne vidove energ...

U radu su obrađena palinoloških istraživanja vezana za definisanje tipova i vrsta biljne vegetacije od koje su nastali ugljevi na području Ugljevika, kao i vremena nastanka, vrste i kvaliteta ugljeva na prostoru Ugljevičkog basena. Posebnim naučnim metodama su povezane određene definicije i pojmovi, analizirana projektna dokumentacija, povezane rel...

Interes za pojave ugljeva na širem području Novog Šehera je prisutna duži niz godina ali  eksploatacija nije ostvarena. Značajna detaljnija istraživanja su posljednji put izvedena u periodu 1982 i 1988. godine, i finansirali su ih „Natron“ iz Maglaja i Rudnik mrkog uglja „Đurđevik“ iz Đurđevika. Na osnovu interesa investitora, detaljna geološk...
