Contribution to the understanding of the impact of coal mining on water resources
Maričić Tamara
Coal is the dominant source of electricity in the world and in Serbia. Coal mining has multiple adverse impacts on water resources including: alterations in the hydrological regime (cutoff or watercourse displacement), alterations in the hydrogeological regime (lowering of groundwater levels and yields of the surrounding aquifers) and deterioration of the underground and surface waters quality (pollution due to infiltration or direct inflow of polluted mine water). These impacts can be direct and indirect, primary, secondary and extraordinary. Special attention should be paid to rehabilitation and remediation of mines upon their closure, as well as to the monitoring of the quality of surrounding water bodies. In addition to the analysis of various aspects of the impact of coal mining on water resources, this paper deals with the possible protection measures that need to be applied in order to prevent or reduce the expected negative impacts of exploitation. Certain examples of coal mines in Serbia have also been discussed.
