Abstract

HORTKORN, F.  and  NARAINSAMY, Y.. A review of EN 16907 on earthworks (extractive waste) in the context of South African mine residues. J. S. Afr. Inst. Min. Metall. [online]. 2022, vol.122, n.6, pp.291-298. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/1881/2022.

Rather quietly, a new generation of European norms dealing with earthworks has been developed over the past few years, in particular a part of EN 16907 pertaining to extractive waste. Whereas the majority of the parts deal with routine geotechnical aspects, one part deals specifically with tailings dams. The standard is currently in draft form but if this becomes a European Standard, members of the European Union are bound to comply with the regulations. As such, the standard has the capacity to influence mining in Europe and potentially in South Africa. In this paper we review the standard and compare it to the South African standard on mine residues and the recently published Global Industry Standard on Tailings Management (GISTM). We conclude found that although the European norm makes great strides towards increasing tailings dam safety, there is room for improvement. The current South African standard has served well since its inception, but can be improved by using concepts from the European and global tailings standards.
