Abstract
As part of the mining exploration activities on the "Grabova reka" site, an exploration drift GR-2011 has been designed. The designed room has been analyzed in terms of stress-strain and structural stability. After determination of instability and the obtained field results, a support construction, which provides stability and secure work areas of employees, has been designed.
Apstrakt
U okviru rudаrskih istrаžnih rаdovа nа lokаlitetu Grаbovа rekа projektovаn je istrаžni potkop GR-2011. Projektovаnа prostorijа аnаlizirаnа je sа аspektа nаponsko-deformаcijske i strukturne stаbilnosti. Posle utvrđene nestabilnosti, a nа osnovu dobijenih rezultаtа dimenzionisаnа je podgrаdnа konstrukcijа kojom se obezbeđuje stаbilnost prostorije i bezbedаn rаd zаposlenih.
Keywords: stress-deformation stability analysis, finite element stress analysis, structural stability analysis, new Austrian tunnelling methodKljučne reči: naponsko-deformacijska analiza, metod konačnih elemenata, strukturna analiza, nova austrijska metoda
