Abstract:
Slurry pipeline technology has evolved over the past 50 years and prediction methods for all types of slurries, ranging from coarse solids in water to highly non-Newtonian slurries, are reasonably well developed. In comparison, prediction methods for tailings flow down a beach and the resulting beach slope, are less well developed although the two types of flow are obviously related to some extent. The current paper analyses open channel flow down a tailings beach using approaches developed for pipe flow. Predictive slope equations are presented. The resulting predicted slopes are compared with a range of measured slopes in both flume experiments and tailings deposit slopes at a number of operating mines.
