DVOFACEK, J. et al. Water production as an option for utilizing closed underground mines. J. S. Afr. Inst. Min. Metall. [online]. 2022, vol.122, n.10, pp.571-578. ISSN 2411-9717.  https://doi.org/10.17159/2411-9717/1439/2022.

Each mining project goes through the same life-cycle, from prospecting and exploration to closure and post-closure periods. This prompts the question whether the closure of a mine constitutes the end of its life-cycle or whether the decommissioned mine can be employed for some other purpose. Best-practice references indicate that there are many viable options. In our opinion, the production of service water is one such option. Laboratory research was carried out on the water from a flooded underground coal mine in Ostrava-Karvina coal district, Czech Republic, concerning the production of service water from pumped mine-water. The research proved the practical feasibility of service or process water production. Given the effect of global climate change with regard to water resources, good prospects for this additional resource can be assumed since the water has to be pumped in any case for safety reasons.

Palabras clave : underground mine; mine closure; service water production.
