Приказ коморно-стубне методе откопавања са подетажним откопавањем стубова и накнадним засипавањем откопа
Милош Вуковић (2024)Коморно-стубна метода откопавања са подетажним откопавањем стубова се користи за рудне жиле и сочива, стрмог пада.У овом раду су приказани основни елементи примењене методе откопавања као што су: димензионисање просторија припреме, бушачко-минерски радови,утовар и транспорт,вентилација и запуњавање откопаног простора паста засипом. Анализом трошкова прорачуната је цена израде припремних просторија, по дужном метру, на основу квалитета радне средине у којима се израђују. Такође, анализирани су трошкови при експлоатацији руде и приказани су јединичном вредношћу USD/t (долара по тони руде).На крају ...... yHyrTpatier Tpehba, (”) Ta6ena 4 Ifapawempu paone cpeoune oO d |a| 9 |2i ss B - |Ig - ai::507] ŽE OO E | DB|REP Š Bpcra noarpane = zi S q Fa - o = > O c Y H (0] >)|)4 (MPa) (kN/m*) | (m) () I 5 24,00 780 65 10,6 >» |4 TopkpeT OeTOH |i! 4 23,00 780 60 5,379 |> |4 TopkpeT OeTOH 14 3.2 ...

Development of the Availability Concept by Using Fuzzy Theory with AHP Correction, a Case Study: Bulldozers in the Open-Pit Lignite Mine
Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović (2019)Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space. Usually, availability is shown as the ...... O = 175.

Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

Geotehnički uslovi izgradnje nadvožnjaka "Balajnac" na autoputu E-80 deonica: Niš - Merošina
Dragoslav Rakić, Nikola Božović (2024)U sklopu prve deonice autoputa E-80 Niš – Merošina, izgrađen je nadvožnjak u zoni sela Balajnac koji je oslonjen na tri stubna mesta na međusobnom rastojanju od oko 26 m. Svaki stub je fundiran na šipovima i to sa predloženim rasporedom od 2 šipa u grupi na međusobnom rastojanju od 3.6 m. U radu su na osnovu izvršenih geotehničkih istraživanja terena, analizirani rezultati nosivosti vertikalno opterećenog šipa prečnika 1.2 m i dužine šipa od L = 23 m.
