Geotechnical data on copper, uranium, and phosphate tailings from 41 mines were collected and analyzed to empirically establish the variability in strength properties for tailing embankments. These data were analyzed both from geotechnical and statistical perspectives to infer typical strength parameters for slope stability analysis. The results indicate large variability of strength properties both within and among tailings embankments. However, this variability in most cases appears statistically regular and tends toward normal distributions when spatial trends are removed. The implication is that probabilistic techniques can be used to assess the importance of strength property variability for embankment stability and that the assumption of common distributional forms for input to such modeling is appropriate.
