Belem, T, Fourie, AB & Fahey, M 2010, 'Time-dependent failure criterion for cemented paste backfills', in R Jewell & AB Fourie (eds), Paste 2010: Proceedings of the Thirteenth International Seminar on Paste and Thickened Tailings, Australian Centre for Geomechanics, Perth, pp. 147-162, https://doi.org/10.36487/ACG_rep/1063_13_Belem (https://papers.acg.uwa.edu.au/p/1063_13_Belem/) Abstract: In this paper, a simple time-dependent failure criterion has been proposed for cemented paste backfills. In addition to curing time, it allows to take into account the binder content that will be responsible for the material strength development. The properties described by this time-dependent criterion are those undrained since the backfilled mine stopes have been categorised as undrained in long term.
