ABSTRACT: This paper presents experimental results from free and restrained shrinkage tests conducted on tailings. The laboratory technique used here has been recently developed to assess the desiccation of tailings from hard rock mines. Sample results obtained with this testing procedure are presented and compared with results from a pressure plate extractor test performed on the same tailings. Comparison between experimental data and numerical simulation results is also used to analyze the unsaturated behaviour of tailings subjected to desiccation.
RÉSUMÉ: Ce papier présente des résultats expérimentaux issus d'essais de retrait libre et contraint réalisés sur des échantillons de résidus miniers. La technique de laboratoire utilisée ici a été récemment développée pour évaluer la dessiccation de résidus de mines en roche dure. Quelques résultats sont présentés et comparés à ceux d'un essai en cellule de pression réalisé sur les mêmes résidus. Une comparaison entre les résultats expérimentaux et ceux de simulations numériques sert aussi à analyser la réponse non saturée des résidus miniers en phase de dessiccation. 1 INTRODUCTION
