Title Passive mine water treatment as an alternative to active systems Type Journal Article
Year 2002 Publication Grundwasser Abbreviated Journal
Volume 7 Issue 2 Pages 67-77
Keywords Groundwater quality geographical abstracts: physical geography hydrology (71 6 11) water treatment groundwater pollution water quality mine
Abstract For the treatment of contaminated mine waters reliable treatment methods with low investment and operational costs are essential. Therefore, passive treatment systems recently have been installed in Great Britain and in Germany (e.g. anoxic limestone drains, constructed wetlands, reactive barriers, roughing filters) and during the last eight years such systems successfully treated mine waters, using up to 6 ha of space. In some cases with highly contaminated mine water, a combination of active and passive systems should be applied, as in any case the water quality has to reach the limits. Because not all the processes of passive treatment systems are understood in detail, current research projects (e.g. EU-project PIRAMID) were established to clarify open questions.

Title Acid mine drainage prevention and control options Type Journal Article
Year 2002 Publication CIM Bull. Abbreviated Journal
Volume 95 Issue 1060 Pages 96-102
Keywords acid mine drainage prevention tailings environment waste sulphides Groundwater problems and environmental effects Pollution and waste management non radioactive Surface water quality Waste Management and Pollution Policy tailings sulfide mining industry waste management
Abstract Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at operating and closed/decommissioned mine sites. AMD may adversely impact the surface water and groundwater quality and land use due to its typical low pH, high acidity and elevated concentrations of metals and sulphate content. Once it develops at a mine, its control can be difficult and expensive. If generation of AMD cannot be prevented, it must be collected and treated. Treatment of AMD usually costs more than control of AMD and may be required for many years after mining activities have ceased. Therefore, application of appropriate control methods to the site at the early stage of the mining would be beneficial. Although prevention of AMD is the most desirable option, a cost-effective prevention method is not yet available. The most effective method of control is to minimize penetration of air and water through the waste pile using a cover, either wet (water) or dry (soil), which is placed over the waste pile. Despite their high cost, these covers cannot always completely stop the oxidation process and generation of AMD. Application of more than one option might be required. Early diagnosis of the problem, identification of appropriate prevention/control measures and implementation of these methods to the site would reduce the potential risk of AMD generation. AMD prevention/control measures broadly include use of covers, control of the source, migration of AMD, and treatment. This paper provides an overview of AMD prevention and control options applicable for developing, operating and decommissioned mines.

Title Einsatz alkalischer Substanzen zur Verbesserung der Wasserqualität in Bergbaukippen. Use of alcine substances for the improvement of water quality in mining areas Type Journal Article

Abstract Eisendisulfidminerale im Abraum von Braunkohlentagebauen können nach ihrer Verwitterung im wiederaufsteigenden Grundwasser erhebliche Güteverschlechterungen hinsichtlich pH-Wert, Schwermetall- und Sulfatgehalt verursachen. Diesen kann durch Zusätze alkalischer Substanzen zum Abraum wie Kalkstein, Dolomit und Kraftwerksasche bzw. Gemischen dieser Stoffe entgegengewirkt werden. Die Ergebnisse entsprechender Untersuchungen sowie die naturwissenschaftlichen Grundlagen der Eisendisulfidverwitterung werden im Beitrag dargestellt und ein Anwendungsbeispiel beschrieben. Grundlagen zur Berechnung der einzusetzenden Kalk- oder Aschemengen (bzw. Gemische der beiden Substanzen) sind die Bestimmung der oxidierbaren Sulfidminerale in den einzelnen geologischen Schichten sowie die Bestimmung der Pufferkapazität der Asche bzw. des Kalksteins. Besonders Vorteilhaft ist der Einsatz alkalischer Substanzen dort, wo durch vorhandene hohe Pyrit- und Markasitkonzentrationen mit einer erheblichen Versauerung des Grundwassers gerechnet und dadurch eine potentielle Beeinträchtigung von Grundwassernutzern erwartet werden muss. Solche Bedingungen sind im Rheinischen Braunkohlerevier, insbesondere im Umfeld des Tagebaus Garzweiler II (RWE Rheinbraun AG) gegeben. Derzeit werden im Tagebau Garzweiler bereits 40000 t Kalkstein dem Abraum beigemischt. Auch für das Lausitzer Braunkohlenrevier könnte ein Einsatz alkalischer Substanzen in Betracht gezogen werden.
