Analysis and visualization of geophysical well-logging data from closely spaced boreholes
Geophysical logging measurements for determining the condition of the rock mass on the dam profile and locating the predisposed directions of water circulation and loss from the reservoir were conducted in four boreholes distributed at a close distance. The survey was carried out in a typical karst terrain, which is an additional challenge for defining the geological model, especially in terms of water retention.

Geotehnički aspekti izgradnje visećeg pešačkog mosta u Starom gradu u Užicu
U radu su prikazani rezultati geotehničkih istraživanja za potrebe izgradnje visećeg pešačkog mosta preko klisure reke Đetinje u Užicu. Predviđeno je da most, sistema prednapregnute trake, omogući prelaz pešacima sa desne dolinske strane na stranu Starog grada, koja je opasana strmom liticom (cca. 40 m visine). Za potrebe formiranja geotehničkog modela i strukturnog sklopa krečnjačke stenske mase korišćen je postupak fotogrametrijskog snimanja dronom.

Modern self-propelled surface drill rigs for drilling small diameter holes in mining and construction operations
Milanka Negovanović, Lazar Kričak (2021)Приликом одређених рударских или грађевинских радова потребно је извршити минирање применом бушотина малог пречника. Раније, бушење бушотина малих пречника се изводило углавном ручним бушилицама или лаким лафетним бушилицама нa одређеним нoсачима. Проблеми у овим случајевима били су капацитет бушења, бушење већих дужина бушотина и посебно безбедност оператера на неприступачним теренима, где је његово присуство било неопходно. Данас постоје модерне самоходне бушилице за бушење минских бушотина малог пречника, које су у потпуности даљински управљане.

Analiza seizmičkog dejstva eksplozije pri miniranju na primeru izrade tunela Golubac kod Golupca
Savremeno rudarstvo, a pogotovo masovna eksploatacija metaličnih ležišta, ne bi se mogla zamisliti bez primene eksploziva. Rudarstvo je privredna grana, gde su eksplozivi našli najširu primenu za eksploataciju čvrstih mineralnih sirovina. Primena energije eksploziva dovodi do poboljšanja tehničkoekonomskih pokazatelja pri eksploataciji mineralnih sirovina, ali i do pojave negativnih efekata koji prate radove na miniranju. Eksplozivni materijali u rudarstvu, geologiji i drugim delatnostima, svojim dejstvom narušavaju prirodnu sredinu u vidu drobljenja, razbacivanja komada stene, vazdušnih udara, pojave sezmičkih efekata, pojave ...Suzana Lutovac, Miloš Gligorić, Jelena Majstorović, Luka Crnogorac.

Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija... induced by the rock stress surrounding the gate road.
