abstractsOne of ways to reduce the capacity of tailings being deposited into a disposal is change of deposition technology aiming at discharging denser material with reduced amount of water. It may be executed by preliminary thickening of tailings up to the form of paste. However, discharging denser material and its deposition on top of tailings which were previously spigotted requires an assessments of its bearing capacity. In order to verify this issue in situ model tests in TSF Żelazny Most, Poland have been performed. The response of saturated tailings to additional surcharge corresponding to deposition of paste material has been modelled by trial inward embankment 1100 long constructed on the surface of spigotted tailings. Consolidation and deformation conditions were identified based on SCPTU, SDMT, FVT tests accompanied by embankment settlement measurements supplemented by laboratory testing of tailings samples. The results of tests have revealed variety of tailings responses depending on its location and deposition conditions.
