With coal resources steadily becoming depleted, opencast coal mines in South Africa will approach a period of mass closure, inevitably impacting on groundwater resources Stacey et al., 2010, Vermeulen and Usher, 2005. Post-mining management and predicting the mine water quality after backfilling opencast coal mines therefore becomes imperative.
