North Rhine-Westphalia is a post-mining state: intensive raw material mining has left its mark especially in the Ruhr region and the Rhenish mining area. “When mining goes, what remains are challenges such as ground movements, large opencast mining lakes, disused sites of industrial culture or the so-called eternity tasks. At the same time, however, there are also many opportunities to ...

Drone pilot Bodo Bernsdorf sees the world through different eyes. When he lets his special copter soar high above the grounds of the Zollverein coking plant in Essen/Germany, he not only encounters the chimneys and pipelines at flying height – he also finds damaged areas that are not even visible to the naked eye (Figure 1). The drone’s high-resolution images ...

Resources are becoming scarcer, energy prices are rising. In addition, dependence on third countries has led to a global rethink when it comes to extracting raw materials. New ways must be found to extract valuable materials ecologically and economically. That these ways also follow unusual ideas is shown by a new project that has now started at the Research Center ...

Coldewey, W. G. (2022): Handbuch Hydrogeologie. Das Standardwerk für Lehre und Praxis. First edition. 713 pages, 104 tables, 178 figures and 42 appendices. Vulkan Verlag GmbH Essen (Figure 1). The importance of water as a geo-resource for the people and the environment has been emphatically brought to the attention of the public in recent years. The orderly handling of water ...

Mining leaves its mark – water in particular as a resource in the former mining regions is affected by the consequences of intensive raw material extraction, some of which has been ongoing for centuries. The key issues in this year’s “NACHBergbauzeit in NRW” conference (Figure 1) looked at the challenges involving the long-term management of water and the resulting effects ...

At the Research Center of Post-Mining (FZN) at TH Georg Agricola University (THGA), Bochum/Germany, Julia Tiganj (Figure 1) is studying the socio-economic aspects of post-mining. In times of raw material scarcity and the energy transition, the economics researcher’s attention is especially drawn to China. Will the world’s second-largest economy manage the transition to renewable energy? What are the greatest challenges ...

The ground below Gronau and the surrounding area is a challenge, even for geologists: Salt has been mined here intensively for almost 50 years. This has created large cavities, known as caverns, at depths of between 1,000 and 1,500 m. Most of them are now used to store natural gas, crude oil or helium, and are important to the economy ...

Intensive mining has caused the terrain and surface to sink so substantially in some areas in the Ruhr area that large depressions have formed – referred to as polder areas. In these areas, waterways cannot always flow freely anymore. The “lower” areas therefore need to be continuously artificially drained to prevent the accumulation of water from rivers and lakes. These ...

Our underground is on the move. However, the shocks are often so small and spatially restricted that they are only detectable for very sensitive sensors. Even where mining was once conducted and people interfered with the natural geology and deposits, it may subsequently cause microseismic shocks. Paloma Primo, scientist at the Research Center of Post-Mining (FZN) at the TH Georg ...

Save the date: Bereits zum sechsten Mal veranstalten die Technische Hochschule Georg Agricola (THGA) und die Bezirksregierung Arnsberg ihre gemeinsame Fachtagung. Thema diesmal: „Grubenwasser – analog gedacht, digital diskutiert!“ Dazu treffen sich die Expertinnen und Experten dieses Mal ausschließlich online! Wie gelingt ein verantwortungsvoller Umgang mit den Folgen des Bergbaus? Und welche Perspektiven bietet die Nachbergbau-Ära für Mensch und Umwelt? ...
