Application of Modern Geo- and Environmental Monitoring Methods for the Sustainable Management of Geological Resources
The sustainable management of geological resources presents a challenge for environmental and geomonitoring actions with all the diverse tasks and assignments involved, such as water management and the monitoring of environmental changes. Today’s geo- and environmental monitoring processes involve the observation of many different factors and use satellite-supported optical remote…

Risk Management of Abandoned Mines: 2020 and 2019 – Between Requirement Analysis and Expert Reports on the Impact Relevancy of Abandoned Mines
In 2011, the NRW mining authority initiated the systematic analysis and evaluation of surface fracture relevant shafts within the state of North Rhine-Westphalia’s area of responsibility as part of risk management regarding potential hazards of abandoned mines. The measures that have been taken subsequently aim to, amongst others, prevent physical…

Mining Residues, Reprocessing and Related Projects at the BGR
Residues from the mining industry can be separated into waste rock, tailings and stockpiles. These different materials are usually stored separately from one another within the mine site. Where this has not been done – which is sometimes the case in older mines – the subsequent sorting and processing operation…

Mineralogical and Micro-Mechanical CharacteriÂzation of Slags – Investigated on the Example of a MnSiFe Slag from Electric Arc Furnace
Recently, the recycling of metallurgical residues, e. g., electric arc furnace slag, has gained increasing importance. The potential of metallurgical slags often lies, in addition to the metallic value content, among other things in their use as aggregates for the construction industry, e. g., cement industry. The development of this potential requires…
