Abstract
The stability of potash tailings piles is investigated using a pore-wa ter pressure generation and dissipation model together with a limit eq uilibrium analysis. It is found that a shallow toe failure mode is gen erally the most applicable and that the stability may be influenced by pore-water pressure migration below the pile. It is suggested that fi eld studies would be useful in evaluating stability in the toe region of the pile.
