Lacy, HWB & Barnes, KL 2006, 'Tailings Storage Facilities ⎯ Decommissioning Planning is Vital for Successful Closure', in AB Fourie & M Tibbett (eds), Mine Closure 2006: Proceedings of the First International Seminar on Mine Closure, Australian Centre for Geomechanics, Perth, pp. 139-148, https://doi.org/10.36487/ACG_repo/605_6 (https://papers.acg.uwa.edu.au/p/605_6_Lacy/) Abstract: A major driver for improved planning in closure of Tailing Storage Facilities (TSFs) is that as result of centuries of mining, countless thousands of these particular legacies exist around the world. Rather than increase the number of these legacies and to arrest this problem, implementation of robust decommissioning programmes is required, and in the case of reprocessing or re-mining - the placement of the reworked materials in a safe, stable state is warranted.
