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.

Ground surface subsidence monitoring using sentinel-1 in the “Kostolac” open pit coal mine
Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić (2023)Open pit coal mining affects surrounding populated areas, resulting in terrain surface deformation. Surface deformation should be monitored as often as possible to control deformations and prevent potential incidents. This paper analyzes time series deformation estimated from the Sentinel-1 satellite images using the Persistent Scatterer Interferometry method to monitor subsidence rates caused by open pit mining activities. It is possible to measure deformations using classical geodetic methods, but those are rarely used in practice because they are time-consuming and ...Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić.

Стратешко планирање функционалности подземних просторија моделом прогнозе деформација
Лука Црногорац (2023)Релативно велике деформације подградне конструкције у подземним рудницима угља у Републици Србији представљају један од главних проблема за постизање планиране производње угља. Деформације подграде су директна последица статичких и динамичких оптерећења стенске масе и у многоме зависе и од времена трајања изложености подграде утицају подземног притиска. Код ниско механизованог радног процеса долази до повећаног излагања подземних просторија утицају подземног притиска услед дугог производног циклуса који је често пропраћен застојима у раду.

Determining seismic hazard in slowly deforming region: Can we gather enough information from karst caves?
Ana Mladenović, Jelena Ćalić (2021)Methods to determine seismic hazard in any region vary depending on the regional seismicity, but can be roughly grouped into two main groups: one based on probabilistic methods that use data about known seismicity in the region, and another, which is based on data related to the faulting processes and determination of seismically active faults. Both groups of methods are relatively good for seismically active regions. However, in regions of low seismic activity and slow deformations, there is neither ...Ana Mladenović, Jelena Ćalić.

The Late Devonian contraction along the Precaspian Basin north margin: Transpressional range building in the intracratonic domain
Novak Novčić, Marinko Toljić (2023)The evolution of intraplate sedimentary basins located in the vicinity of an active convergent plate boundary is often controlled by the collisional dynamics of the adjacent orogen. The transfer of compression from the orogen to the platform's interior results in the formation of complex structural geometry and kinematics that often reactivate older crustal faults, focus far-field stresses and control the evolution of associated sedimentary basins. One place where this localisation can be optimally understood is the Precaspian Basin, situated ...Intrakratonske deformacije, transpresija, kosa kompresija, krustalni rasedi, intrakratonski transfer stresa, kontrakcioni blokoviNovak Novčić, Marinko Toljić.

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... ted series of the support deformations.

The different approaches in seismic stratigraphy interpretation
Dejan Radivojević (2018)U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.seizmostratigrafija, istraživanje nafte i gasa, karakteristične seizmičke sekvence, seiz-mofacijalna analiza... pp 297, Oxford, 2001.

Analiza seizmičkog dejstva eksplozije pri miniranju na primeru izrade tunela Golubac kod Golupca

Rudarstvo je privredna grana, gde su eksplozivi našli najširu primenu za eksploataciju čvrstih mineralnih sirovina.

Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations
The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit.
