Stability check and support designing for the GR-2011 exploration drift
Keywords:
stress-deformation stability analysis; finite element stress analysis; structural stability analysis; new Austrian tunneling method
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.
