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).

Present prospects and tendencies in the field of gateroads securing in coal mines
Šňupárek, Richard
The paper deals with methods of supporting and stabilisation of roadways in coal mines.New investigated and designed methods are connected with double usány of roadways, depth of exploration and environmental requests.Decisive kinds of support include methods of rock mass strenghtening e.g. bolting and grouting.
