| Short description: |
Predicting heavy metal transport from underground mines using traditional reactive transport models is difficult, as two transport routes must be accounted for. Shafts and drifts within the mine could provide fast flow pathways to the accessible environment whereas the rock matrix, which is the source of contamination, is characterised by relatively slow flow. The interaction between these two regimes is crucial for understanding the transport of metals and radionuclides. The hybrid reactive transport model presented in the paper simulates equilibrium speciation reactions, allowing the simulation of geochemical mixing. Speciation distributions are shown to be quite heterogeneous in mines and that this heterogeneity could have implications for the mobility of heavy metals and radionuclides.
