... Introduction Hot dry rock (HDR) is an abundant source of geothermal energy, which is normally buried in the depth of 3∼10km (Gringarten, 1975; Smith, 1983; Ghassemi et al. , 2003; Bruel, 2007). Due to the extremely low matrix permeability of HDR, hydraulic fracturing technology is currently an effective...

... Abstract In modern tunneling, the assessment of the structural integrity is usually based on displacement measurements of the tunnel lining using total stations or on readings of electrical strain gages embedded inside the liner. However, these technologies only deliver information...

... Abstract The failure hazard rock burst is very dangerous as it can occur very suddenly and violently. Due to the fact, that tunnel and mining projects are in deeper areas than ever, the importance of investigating this hazard is more relevant than ever. The Graz University of Technology...
