Testing the energy value of different types of coal by the method of active thermography
In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.

Underground loading-haulage equipment selection with application of topsis method with different weighting methods of criteria
The choice of adequate mining machines is one of the most complex problems in the underground exploitation of mineral raw materials. The weight of such a decision is reflected in the high prices of these machines and the occurrence of even greater costs during their use if their choice was wrongly conceived. There are numerous examples from practice in which such decisions were made solely on the basis of comparing the prices of machines, without considering any of the ...utovarno-transportna mehanizacija, izbor, TOPSIS, entropija, standardna devijacija, težina kriterijumaVladimir Krivošić, Luka Crnogorac, Rade Tokalić.

Modeliranje disperzije dimnih gasova iz termoelektrane ,, Nikola Tesla”
Milica Kostić (2024)Termoelektrane na ugalj, iako značajan izvor električne energije, predstavljaju veliki izazov zbog zagađenja koje uzrokuju. Glavni uzrok zagađenja je neumerena ljudska potreba za energijom i resursima, što dovodi do emisije različitih zagađivača u atmosferu, uključujući okside ugljenika, sumpora, azota, kao i lebdeće čestice i toksine. Ove emisije imaju negativan uticaj na kvalitet vazduha, zdravlje ljudi i životnu sredinu.

The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers
One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance.

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 application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... without correction for the angle of incidence, then correcting: for proportion of direct radiation, which equals 1-Pai (ESRI, 2019): R = (Sconu Z(B"))) / (1 - Pai) (7) For the uniform sky diffuse model, Weighto,y, is calculated as follows (ESRI, 2019): Weighto„ = (cos0-- cos0;) / Divai where: ...
