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.

Poreklo asocijacije Ni, Ag i Sn minerala u polimetaličnom ležištu Rudnik
Rudnomikroskopska, SEM-EDS i LA-ICP-MS ispitivanja rudne mineralizacije iz Pb-Zn-Cu-(Ag) ležišta Rudnik, ukazala su na lokalno prisustvo specifične asocijacije minerala nikla, srebra i kalaja, deponovane u tektonskoj breči, arsenopiritsko-pirotinskim, piritsko-pirotinsko-arsenopiritskim i kvarcno-sulfidnim žicama u harcburgitima. U tektonskoj breči deponovan je polimineralni sulfidni agregat kojeg čine pirotin (50), galenit, sfalerit i halkopirit. Arsenopiritsko-pirotinske žice odlikuje dezintegrisani agregat arsenopirita cementovan sa pirotinom. U piritsko-pirotinsko-arsenopiritskim žicama masivni pirit (50%) prorasta sa arsenopiritom i cementovan je polimineralnim agregatom pirotina, galenita i sfalerita.

Fluid inclusion study in quartz of the Rudnik Pb-Zn-Cu-Ag skarn deposit, Serbia
Six types of fluid inclusions were identified in three growth zones of hydrothermal quartz from the Rudnik skarn deposit. In the core zone, primary two-phase fluid inclusions of high (type 1) and moderate salinity (type 2) homogenized to liquid between 350-430 °C and 340-420 °C, respectively. Raman analysis revealed that the vapour phases are a CO2-CH4 gas mixture, with a predominance of CO2. The core contains and dispersed vapour-rich fluid inclusions of low salinity (type 3) composed of CO2-CH4-H2S ...Stefan Petrović, Ronald J. Bakker, Vladica Cvetković, Rade Jelenković.

Application of softwares for drilling and blasting
U današnje vreme softveri se sve više primenjuju u rudarstvu kroz eksploataciju mineralnih sirovina, projektovanje rudnika, u obavljanju različitih operacija na terenu i sl. Među softverima za rudarstvo, postoje softveri za specifične rudarske operacije, kao što su operacije bušenja i miniranja. Ovi procesi su veoma važni u eksploataciji čvrstih mineralnih sirovina, jer predstavljaju najjeftiniji i najefikasniji oblik fragmentacije stenske mase. Kroz rad, predstavljeni su neki od softvera u kombinaciji sa modernim tehnologijama, koje se koriste širom sveta i koje ...Stefan Milanović, Lazar Kričak, Milanka Negovanović, Nikola Simić, Jovan Marković.

Status and tendencies under development and application of underground coal gasification-UCG
Podzemna gasifikacija uglja u Svetu poslednjih decenija doživljava znatnu ekspanziju u istraživanju i razvoju zbog uveliko iskorišćenih ležišta uglja i loših ekoloških efekata (pri sagorevanju u TE) na životnu okolinu. Srbija ima znatne rezerve uglja, a kada bi se za PGU koristile samo vanbilansne rezerve i otkopni ostaci bilansnih, jasno je kakvi bi bili ekonomski (a i energetski i ekološki) efekti. U radu su sagledane aktivnosti u Svetu na tom planu, pa smatramo da ima smisla i potrebe za primenu ove ...David Petrović, Lazar Kričak, Stefan Milanović, Jovan Marković, Nikola Simić.

Application of Expansive Mortars for the Formation of Artificial Screens During Blasting in Urban Areas
During construction of buildings in urban areas, sometimes there is a need to blast solid rock mass in the immediate vicinity of the surrounding buildings. In that case, the aim is not only to increase the efficiency of blasting, but also to reduce harmful effects of ground vibration induced by blasting. At the same time, it is very important to protect the buildings located in the safe zone from the blast site as well as remaining rock mass around ...Milanka Negovanović, Lazar Kričak, Stefan Milanović, Nikola Simić, Jelena Majstorović.
