Application of stochastic models for mine planning and coal quality control
... rameter. Slave parameter for homogenization is coal heating value. The integral model for coal quality control is developed and consists of three sub-models: operational mine scheduling model, stocking model and reclaiming model, fig. 5. According simulated daily or shift mine plan each BWE has working ...
... This model, in general, is based on predicted information about the in-situ quality of the coal deposit. Consequently, production scheduling for the purpose of controlling coal quality, e. g., sulfur, have to be based on the predicted data of the contemplated mining benches. The model uses zero-one ...
... within pile, fig. 2. The shadings of layer's cross-sections in fig. 2 are corresponding to the percentage of sulfur. The reclaiming model Developed reclaiming model determines the tonnage of coal to be loaded from stockyard piles by reclaimer, so that the total sulfur con- tent of the reclaimed ...Dejan Stevanović, Božo Kolonja, Ranka Stanković, Dinko Knežević, Mirjana Banković.

Replica of the “Great Triangle Gold Nugget” Belonging to Belgrade University Collection, Gilded or Not?
... Belgrade in Serbia, has been holding over a hundred years the gypsum model of triangular shape that represents the replica of one of the world’s largest native gold nugget weighing 36.2 kg, known as “The Great Triangle”. Nugget model is golden metallic in colour with a shape similar to a rectangular ...
... Since the gold colour and shine remained the same, did not darken by the time it was assumed that the model is gilded. Material and method Chemical composition of the gypsum model surface was carried out in the Laboratory for SEM, Faculty of Mining and Geology, University of Belgrade ...
... the type and manner of material that was used for covering. Result and conclusion The data obtained by EDS analysis show that the gypsum model is covered with gold leaf, which was expected according to the macroscopic characteristic of the object. How many such gilded replicas of the ...Alena Zdravković, Maja Milošević, Ivana Jelić.

Mitigating hydrate formation in onshore gas wells: A case study on optimization techniques and prevention
Gas wells, particularly those situated onshore, play a vital role in the global energy sector by supplying a significant portion of natural gas. However, operational challenges, notably gas hydrate formation, pose substantial issues, leading to complications such as flowline blockages and unexpected well shutdowns. Gas hydrates, crystalline structures resembling ice, ...Gas Well, Gas Hydrate Formation, Well Modeling, Well Performance Optimization, Choke Position Adjustments, Methanol InjectionMilica Ješić, Bojan Martinović, Stefan Stančić, Miroslav Crnogorac, Dušan Danilović.
