  • Optimizacija i planiranje površinskih kopova stohastičkim modelima

    Dejan R. Stevanović (2015-05-29)
    Savremeno rudarstvo izloženo je stalnom trendu pogoršanja uslova poslovanja.Mogućnost ostvarenja ekonomskih i drugih ciljeva rudarskog projektakompromitovana je stalnim pogoršanjem kvaliteta ležišta na kojima se vršieksploatacija, kao i značajnoj dozi neizvesnosti povezane sa geološkim,ekonomskim i tehničkim parametrima proizvodnje. U ovako kompleksnimuslovima poslovanja, matematički modeli sposobni da odgovore značajnimizazovima, odnosno ponude optimalna rešenja kojima se garantuje maksimalnoispunjenje projektovanih ciljeva, nameću se kao neophodnost.Trenutni, konvencionalni pristup optimizaciji i planiranju površinskih kopovazasniva se na algoritmima, razvijenim sredinom prošlog veka čije je opšteobeležje deterministički ...

  • Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs

    John Nyame (2024)
    The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...

  • Design of the Opencast Coal Mine Drmno Dewatering System

    Vladimir Pavlović, Dušan Polomčić, Tomislav Šubaranović (2014)
    Development of mining in the opencast mine Drmno from Kostolac basin in Serbia is carried out in the increasingly complex geological and hydro geological conditions with the decline of the coal seams to the alluvial part of Europe's largest river Danube. Greater depth and inflow of groundwater significantly increase costs for dewatering facilities construction with the requirement for optimizing of this more and more important surface mining process. Making decision on screen construction in the opencast mine with redesign ...

  • Steel Arch Support Deformations Forecast Model Based on Grey–Stochastic Simulation and Autoregressive Process

    Luka Crnogorac, Suzana Lutovac, Rade Tokalić, Miloš Gligorić, Zoran Gligorić (2023)
    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 ...
