Resumo

DVOřAčEK, J. et al. Economics of mine water treatment. J. S. Afr. Inst. Min. Metall. [online]. 2012, vol.112, n.2, pp.157-159. ISSN 2411-9717.

Mine water poses a significant problem in lignite coal mining. The drainage of mine water is the fundamental prerequisite of mining operations. Under the legislation of the Czech Republic, mine water that discharges into surface watercourse is subject to the permission of the state administration body in the water management sector. The permission also stipulates the limits for mine water pollution. Therefore, mine water has to be purified prior to discharge. Although all mining companies operate mine water treatment plants, there is hardly any utilization of the final effluent. The high expenditure involved in the more sophisticated methods of mine water treatment has fuelled the search for the commercial utilization of the effluent.

Palavras-chave : mine water treatment; economics of treatment process; water utilization.
