Abstract
The presence of clay seams in the roof is especially important for assessing the stability of the excavations in salt and potash mines, since they allow separation as well as horizontal slip. The deformational behavior at clay seams in the roof of excavations was investigated by using actual field measurements made at the Waste Isolation Pilot Plant (WlPP) site. From the in situ deformation measurements, the separation and separation rate across the clay seams in the roof and floor could be estimated by using the technique developed in this study. The horizontal displacement along the clay seams was determined from the deflection measurements and compared with the predictions from a computer simulation using FLAC and clastic beam theory.
