Abstract: Mine water hydraulics and geothermal potential of a deep shaft of the flooded Wolf mine in the Siegerland ore district of the Rhenish Massif in Germany were investigated. The electrical conductivity (EC), temperature, pH, and Eh were logged to 580 m below water table using multi-parameter borehole tools in 2009 and 2015. Some variations were detected, which were interpreted to indicate the inflow of water with almost the same temperature from the neighbouring San Fernando mine. Borehole camera observations showed that the deeper mine levels are directly connected to the shaft and are not blocked by natural or manmade barriers. The temperature was relatively uniform throughout the underground water catchment, but variations were found in pH and Eh. The EC profile was relatively uniform in 2009, but some anomalies were seen in 2015 between the depths of 80 and 220 m, indicating changes to the mine water dynamics. Stratification at a depth of 300 m was inferred from the investigation data. The logging results and calculations suggest that the mine could be exploited to supply sustainable geothermal energy. This flooded mine could supply up to a few gigawatt hours of energy per year, and could be used as an important source of low-carbon energy for heating and cooling nearby properties.
