ABSTRACT
Stabilization of several hundred meters high mountain slopes of crystalline rock above a very large open pit mine in Tertiary brown-coal basin is at present under preparation in north-western Bohemia. A stabilization of the slopes is therefore designed by means of huge anchors which will make a locking together of the labil parts of the slope and the deeper stabil rock mass. The problem with the distribution of great anchor powers into the rock mass could be much simplier if none-prestressed anchors would be sufficient for the stabilization of the slopes. The load from groundwater is considered to be reduced by a drainage effect from anchor drifts. As the model research is able to prove the effect of an anchoring system for the slope stabilization, the performance of such great anchors and the respons of the rock mass to their power effect may be examined only in a big field test in situ.
