Abstract

Tailings dams are an alternative for the final storage of waste produced by the metallurgical mining industry. Unlike water reservoir dams, tailings dams have the particularity of requiring a detailed analysis of the post-operation or closure phase. In this stage, the structure must be as safe as during the exploitation phase, even many years after the economic benefit has ceased. In the present, a significant number of historical cases of tailings dams accidents are known. In several cases, failures were generated by sliding of the dam slope after heavy rains. This article shows a simplified method for the evaluation of the mechanical stability of the embankment wall of a mining dam. The analysis accomplished considers the effect of humidity and suction changes on the shear strength of the materials. Through the implementation of a flow-stability coupled model, it is shown that in the probable occurrence of an extraordinary rainfall event, the studied dam maintains its stability with an acceptable factor of safety.
