... spacing. The latter determines the bulking factor of the displaced roof and thus the maximum caving height. For steeply inclined openings it must be considered whether the caved rock moves down the dip and prevents self-stabilization. Rising water levels in deep abandoned mines may induce seismic events...

... churches (Biet Gabriel Rufael church). For this purpose, the church has been considered as a rock-mass excavated for a quarry or mining site. Due to the high seismicity of the near Ethiopian Rift, stability analysis also took into account the seismic input, according to the indication of Eurocode 7...

Paper presented at the ISRM International Symposium - EUROCK 2013, October 23–26, 2013
Paper Number: ISRM-EUROCK-2013-003
... Abstract In this paper, a rockburst is considered as a complex physical and rock mechanical process. The dynamic stress generated by the seismic load that is caused by a seismic event has to be added to the static stress in the rock mass in order to create this phenomenon. The seismic load...
