Predicting Acid Mine Drainage: Past, Present, Future
Total worldwide liability associated current and future remediation of acid mine drainage (AMD) is approximately 100,000 million US-$. Consequences of failing to predict AMD for individual operations and for the mining industry include unplanned spending on remedial measures and reputational damage. Despite these severe risks, predicting AMD properties of mine…

Density Stratification in Mine Water Bodies as a Contribution to Better Long-Term Water Management
In flooded shafts of the Ruhr-area distinct boundaries between differently mineralised water bodies have been observed at diverse locations. The influx of higher mineralised water from the rock mass and from the mine workings on the one hand and the penetrating less mineralised surface water on the other hand causes…
