Non-Detonating Chemical Mixture for Non-Invasive Methods of Rock Breaking
Within the Innovation developed several different non-detonating chemical mixtures for non-invasive methods of rock breaking. Laboratory and polygon tests gave the satisfactory results and knowledge enough to start the practical experiments in the field. The basis of this innovation is a theoretical assumption that certain chemical mixtures release a large quantity of gases during combustion. If these gases are found in the enclosed space a growing pressure on the walls of the chamber in which combustion takes place will ...Lazar Kričak, Milanka Negovanović, Nikola Simić, Stefan Milanović.

Failure Estimation of the Majdanpek Open Pit East Face Based on Inverse Velocity Model
The Majdanpek open pit mine south district is currently active mining prospect of copper ore exploitation in eastern Serbia. Its depth is approaching the termination depth and occurrences of large-scale instabilities and global instability of the final pit slope is possible. These can generate catastrophic mass movement inside an area that encloses a regional road route and the Pek River bed which is channelled along the outer contour of the pit. The displacements that were noted in early 2023, in the ...Miloš Marjanović, Stefan Milanović, Nikola Simić, Lazar Kričak.

Granatski amfiboliti Bistrice
Jovana Opančina (2024)Predmet ispitivanja ovog završnog rada su granatski amfiboliti Bistrice. Izvršena su petrografska i hemijska ispitivanja s ciljem da se odredi stepen metamorfizma, protolit ispitivanih stena i P-T uslovi nastanka. Ispitivani granatski amfiboliti geografski pripadaju Prijepolju, tačnije nalaze se na ulasku u Prijepolje, mesto Bistrica. Geološka građa obuhvata uglavnom mezozojske tvorevine među kojima se nalaze sedimentne, magmatske i metamorfne stene. Geološki procesi koji su doveli do stvaranja amfibolita su procesi subdukcije i obdukcije koji su se pretpostavljamo dešavali na većim ...Jovana Opančina. Granatski amfiboliti Bistrice, 2024

Tektonska evolucija ugljevičkog basena (Bosna i Hercegovina)
Slobodan Dragić (2024)U radu je prezentovana šira slika tektonske evolucije ugljevičkog basena, kao i Dinarida uopšte. Prikazani su litostratigrafski odnosi istraživanog područja, kao i kratak pregled tektonskih jedinica koje se nalaze u domenu basena. Najveća pažnja posvećena je kinematskoj analizi rasjednih struktura i interpretaciji podataka u svjetlu tektonske evolucije basena. Ugljevički basen zapunjen je oligocensko-miocenskim sedimentima, a njegovu osnovu grade paleozojsko-mezozojske formacije. Najstarije tvorevine na ovom području su permski sedimenti. Trijaski i kredni deponati, uglavnom krečnjaci, reprezent su tvorevina ...... ploča ispod Dinarida može pratiti do Egejskog regiona ı da zapravo predstavlja jedinstvenu cjelinu sa onom koja se subdukuje ispod Helenida (Mladenović, 2015).

Geoloski profil planine Avale (severna Šumadija) - uvid u litostratigrafiju i tektonske strukture
Mezozojske formacije Šumadije dele tektonsko-stratigrafsku evoluciju južnijih delova suture jedinica Adrijskog i Evropskog afiniteta, uključujući gornjojursku obdukciju, krednu subdukciju i paleogenu kontinentalnu koliziju. Finalni rezultat dugovremene evolucije u geodinamički složenom ambijentu su komplikovani tektonski i litostratigrafski odnosi različitih mezozojskih formacija suture. Geološki profil kroz planinu Avalu omogućava uvid u skoro potpunu sukcesiju mezozojskih formacija i prostorne pozicije i kinematiku značajnih tektonskih struktura najsevernijih segmenata suture u Šumadiji.
