Some Comments on Dynamic Stability of Rock Slopes

Original language description

Individual sedimentation cycles in the Miocene coal basin in the Northwest Bohemia, where many of open-pit brown-coal mines are situated, contain sometimes some sideritic mudstone interlayers. In order to facilitate continuous operation of the large excvators, these hard layers must be disintegrated by blasting operations prior to coal seam exploitation. Dynamic effects of these blasting operations on the rock slope stability are evalued according to the critical values of particle velocities for slidding and failure of stripping slopes in the open-pit mines. The source of seismic waves was modelled by a cylindric charge of explosives which was put into borehole and tamped by sand. Seismic waves, namely radial component of particle velocities, generated by explosion were recorded. Resulting values of particle velocities were compared with macroscopic effects of individual explosions on the state of rock slopes which were documented by photos before and after every explosion.
