Simpson's rule application for experimental determining parameters of rock mass oscillation equation at limestone
By its form, the use of explosives has a destructive character. However, energy of chemical explosives is tamed and perfected in many effects, so that is developed a series of activities which work is unthinkable without the use of explosives. In mining industry, explosives are most commonly used for exploitation in hard rock mass. Thereby, large amounts of explosives can be used, especially for mass blasting. The application of large amounts of explosives gives auspicious techno – economic indicators ...working environment, seismic effects of blasting, oscillation velocity, rock mass oscillation equation, Simpson’s ruleSuzana Lutovac, Miloš Gligorić, Jelena Majstorović, Branko Gluščević, 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 serijaLuka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić.

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.

Steel Arch Support Deformations Forecast Model Based on Grey–Stochastic Simulation and Autoregressive Process
Relatively large deformations of the steel arch support in underground coal mines in the Republic of Serbia present one of the main problems for achieving the planned production of coal. Monitoring of the critical sections of the steel arch support in the underground roadways is necessary to gather quality data for the development of a forecasting model. With a new generation of 3D laser scanners that can be used in potentially explosive environments (ATEX), deformation monitoring is facilitated, while ...čelična podgrada, prognoza deformacija, vremenske serije, grey-stohastička simulacija, autoregresija, podzemni rudnik ugljaLuka Crnogorac, Suzana Lutovac, Rade Tokalić, Miloš Gligorić, Zoran Gligorić.

Correlation of uniaxial compressive strength with the dynamic elastic modulus, p –wave velocity and s –wave velocity of different rock types
Knowing mechanical properties of rocks incorporated with ultrasonic waves velocities investigations provide a secure basis for mine modelling. Uniaxial compressive strength, dynamic elastic modulus and ultrasonic waves velocities are just some of the rock properties that indicate on presence of discontinuities, stratification and fissures of rocks. Determining the relationship of these rock properties testing the rock samples that are corresponding to different rock types extracted from different mineral deposits represents the core of this study. In this paper, we ...Jelena Majstorović, Miloš Gligorić, Suzana Lutovac, Milanka Negovanović, Luka Crnogorac.

Primena digitalne fotogrametrije u rudniku Rudnik
Digitalna fotogrametrija, lasersko skeniranje i virtuelizacija sve više pronalaze aktivne uloge u rudarstvu, prvenstveno zbog svoje široke mogućnosti primene. Laserskim skeniranjem i fotogrametrijom snimaju se i kreiraju 3D modeli otkopa, jamskih hodnika, površinskih kopova, površinskih objekata (zgrada, spomenika, predmeta), a vrši se skeniranje celih rudnika koji se rekonstruišu u 3D digitalne modele. Fotogrametrija predstavlja proces fotografisanja objekata pomoću fotoaparata i daljom obradom fotografija u različitim softverskim alatima kreiraju se realne kopije 3D modela objekata ili predmeta u digitalnoj formi.

Primena programa UVSZ pri zaštiti od miniranja
Primena energije eksploziva tj. miniranje, predstavlja osnovni način eksploatacije čvrstih mineralnih sirovina u rudarstvu. Miniranjem se postižu vrlo povoljni tehnoekonomski pokazatelji, koje nažalost prate i negativni efekti miniranja. U cilju zaštite životne sredine potrebno je za svaku radnu sredinu odrediti jednačinu oscilovanja stenske mase pri miniranju. Ova jednačina definiše promenu brzine oscilovanja stenske mase u zavisnosti od rastojanja, količine eksploziva, uslova izvođenja miniranja i geoloških karakteristika stenskeSuzana Lutovac, Miloš Gligorić, Jelena Majstorović, Luka Crnogorac, Rade Tokalić.
