Geocultural Education and Digital Geovisualizations of Mountain Mining Landscapes: From Analog via Digital to Real-World explorations – a conceptional approach

Underground mining supplies essential metals that are indispensable for the energy transition and digital technologies. In this context, mountain landscapes around the globe are profoundly transformed, not only at the surface, but also underground on a large scale. Hidden subsurface landscapes develop progressively below the earth surface. A better understanding of the interconnections between subterranean metal extraction, landscape change, energy use and metal consumption is essential for future visions of sustainable resource management. In the current study, the Harz Mountains in Northern Germany serves as a case study to analyze the development of historical mining landscapes in a spatio-temporal and interdisciplinary context including especially geological, geomorphological, hydrological and cultural aspects. The natural landforms has been transformed significantly by ore extraction forming a new hybrid mining landsape.

The project on mining landscapes is carried out at the UNESCO-World heritage site Samson Mine in St. Andreasberg, which was one of the deepest mines in the 19^th century and shows an almost 400-year mining history of silver. The research results are communicated to a wider public in the museum. In this regard the study is embedded in geographical environmental education (GEE), in which global learning and the Sustainable Development Goals (SDGs) form central components. Historical mining serves as a learning platform to reflect on current challenges of global metal extraction and energy use.

Historical perspectives reveal how mining landscapes have been shaped over centuries, how the rate of extraction increased with technical and social innovations or stagnated due to various crises, and they may show, most important, the cultural drivers of ore extraction. In this regard a geocultural concept for science communication has been developed for the Samson Mining Museum integrating digital forms of geovizualisations such as Structure-from-Motion (SfM), GIS-Applications and Augmented Reality (AR). They have the potential to make the underground visible and at the same time to show landscape changes over longer time periods. The fundamental starting element of the educational concept is the staff-guided mine tour through the original historical mine as an authentic and emotional experience. The didactic progression consists of the real-life experience in the mine, followed by locating, capturing, understanding, contextualizing, and reflecting mine-related topics in a local to global context through hybrid digital media in the museum to enhance geographical core competences, and finally transferring the acquired knowledge and interconnections to the real landscape – from Analog via Digital to Real-World explorations (ADR-Concept). The project is supported by fundings schemes on cultural heritage in Lower Saxony by the Ministry of Science and Culture of Lower Saxony (zukunft.niederdsachsen.de).
