Bezbednosna rastojanja u jamskim magacinima eksploziva u domaćoj i međunarodnoj praksi
Projektovanje jamskih magacina eksploziva predstavlja složen inženjerski problem. Sama namena jamskih magacina zahteva ispunjenost niza uslova koji se odnose na bezbedno pozicioniranje magacina, ispunjenost uslova ventilacije, pristupa, rukovođenja magacinom, načina skladištenja eksplozivnih sredstava, protivpožarne zaštite, elektro zaštite itd. Veoma važan parametar prilikom projektovanja jamskih magacina eksplozivnih sredstava predstavlja minimalno sigurnosno rastojanje između susednih komora u kojima su smeštena eksplozivna sredstva u cilju sprečavanja potencijalnog neželjenog dejstva vazdušnog udarnog talasa, razornog dejstva eksplozije i seizmičkog dejstva eksplozije. U ovom radu su prikazani ...... eksplozivnih materija u komorama podzemnih magacina, odnos površina poprečnog preseka eksploziva i komore ide od 1:3,3 do 1:3,5. U praksi ovaj odnos je gotovo uvek veći i retko je kad ispod 1:4, te se može računati da je svega 20 do 25 % preseka komore ispunjeno eksplozivom. Pored toga što se eksplozivno ...

Развој хибридног модела за оптиматизацију завршне контуре одлагалишта у површинској експлоатацији лежишта минералних сировина
Aлександар Додеровић (2024)Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити.

Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules
The stability analysis of homogeneous rock slope following the Hoek–Brown failure criterion under the hypothesis of different flow rules is performed based on limit equilibrium and finite element methods. The applied failure criterion is the generalized Hoek–Brown that can be introduced as a shear/normal function in analysis applying different flow rules. The results are compared with those obtained by the application of equivalent shear strength parameters of the Mohr–Coulomb criterion, considering that this is still the most widely used ...Kružna klizna površ, Huk-Braunov kriterijum loma, Kriterijum popuštanja, Smičuća/normalna funkcija, Nivo napona, Verovatnoća i parametarska analizaSvetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón .

On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions....

Geostatički proračuni sanacije klizišta šipovima
U ovom radu su, polazeći od rezultata geotehničkih istraživanja, prikazani geostatički proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Stoga se simultano analiziraju stabilnost klizišta i stabilnost šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne uslove u tlu i može da se primeni u složenim geološkim uslovima koji su česti u Srbiji.
