| Abstract |
In der Regenzeit 1991/1992 wurden überraschend im Bereich des australischen Goldbergwerks Pine Creek saure Grubenwässer festgestellt, die eine ernsthafte Umweltgefährdung und einen deutlichen Anstieg bei den Betriebskosten verursachten. Diese sauren Grubenwässer traten als Folge von Laugungserscheinungen in den Halden auf. Zur Verminderung der Reaktionsfähigkeit der sulfidischen Berge wurde beschlossen, die Halden mit mehreren Schichten inerten Materials geringer Permeabilität abzudecken. Diese Abdeckung wurde anschließend verdichtet und begrünt. Bei den späteren Abbauarbeiten wurde eine prophylaktische Minimierung der begünstigenden Reaktionsbedingungen vorgenommen. Es wurde eine Integration von Abbau und Sanierungsmaßnahmen realisiert, bei der offene Tagebauflächen mit Haldenbergen verfüllt wurden. Die haldengefüllten Tagebaurestlöcher wurden außerdem teilgeflutet, um den Sauerstoffzutritt zu minimieren. Aus den gewonnenen Erfahrungen wird die Schlußfolgerung gezogen, das AMD-Problem bereits in der Planungsphase zu berücksichtigen und umfassende Untersuchungen einzuleiten. Es sind nicht erst im Stadium der Sanierung, sondern bereits bei den Abbauaktivitäten geeignete Maßnahmen einzuleiten, um unangenehme Überraschungen durch saure Grubenwässer, die übrigens sehr teuer werden können, zu vermeiden. |

| Abstract |
Mining usually causes severe anthropogenic changes by which the ground- or surface water might be significantly polluted. One of the main problems in the mining industry are acid mine drainage, the drainage of heavy metals, and the prediction of mine water rebound after mine closure. Therefore, the knowledge about the hydraulic behaviour of the mine water within the flooded mine might significantly reduce the costs of mine closure and remediation. In the literature, the difficulties in evaluating the hydrodynamics of flooded mines are well described, but only few tracer tests in flooded mines have been published so far. Most tracer tests linked to mine water problems were related to either pollution of the aquifer or radioactive waste disposal and not the mine water itself. Applying the results of the test provides possibilities f or optimizing the outcome of the source-path-target methodology and therefore diminishes the costs of remediation strategies. Consequently, prior to planning of remediation strategies or numerical simulations, relatively cheap and reliable results for decision making can be obtained via a well conducted tracer test. < copyright > 2005 Elsevier GmbH.

| Abstract |
Experiences gained by the UK Mining Industry and effluent treatment companies in theuse of wetlands for treating minewaters are discussed. Discharges from abandoned mines is a major cause of freshwater pollution in some regions. Key topics relating to the use of wetlands for minewater treatment will be discussed at a CIWEM conference in Newcastle on 5 September 1997. |
