ABSTRACT
The backfilling of mine stopes with tailings-cement mixtures, known as paste backfill, has become a common practice
throughout the mining industry. Backfilling was initially used to enhance ground stability and is now frequently used as an
alternative to tailings surface disposal as well. Knowledge of the stresses imposed by backfill on the walls of stopes is
essential for ground stability analysis and for predicting the hydro-geotechnical response of the fill material. Existing
analytical solutions for the pressures in backfilled stopes are only applicable to (sub)vertical stopes. This paper presents
an analytical solution based on limit equilibrium theory and which is applicable to vertical and inclined stopes. The
proposed solution is compared with the results of numerical modelling and with other existing analytical solutions.
RÉSUMÉ
Le remblayage de chantiers souterrains avec un mélange de résidus miniers cimentés, appelé remblai en pâte, est
devenu une pratique courante dans l'industrie minière. Initialement utilisée pour améliorer le contrôle du terrain autour
des chantiers, cette technique est maintenant fréquemment considérée comme une alternative à l'entreposage des
