Valley-fill heap leaches built in steep terrain over low-friction angle liner system may be unstable even though analyses indicate stable ore slopes. This paper demonstrates the potential for massive heap failure using stability analyses which consider both heap slope and heap mass failure considerations. The computations presented also reveal the sensitivity of mass heap stability to liner friction angles.
