Probabilistic designing of bolted support
Janas, P. ; Krejsa, M. ; Šňupárek, Richard ; Krejsa, V.
The paper briefly reviews one of the proposed methods of probabilistic reliability assessment of anchoring reinforcement usable in mine excavations and undergroundworkings. Application of this koncept – software „Kotvení“ (Anchoring) was especiallydeveloped for this purpose usingDirect Determined Fully Probabilistic Method (DDFPMB).
Seismic Loading of Underground Bridge above Medieval Mine
Knejzlík, Jaromír ; Lednická, Markéta ; Kaláb, Z.
Problems with high seismic load in the medieval Jeroným mine working were generated also by heavy trucks on the road above the mine. Because damages of road occurred above the near shallow mine spaces, the road was supported by underground bridge. This paper describes experimental seismic measurements that was targeted the traffic loading of underground spaces.
