Extracting important valuable substances from mine water: New project at the THGA’s Research Center of Post-Mining

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 ...

Online exchange: The “NACHBergbauzeit in NRW” specialist conference focussed on pit 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 ...

“A ‘green’ China can drive the whole world to change”

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 ...

What is causing the ground motion in Epe cavern field?

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 ...

For mankind and the environment: The Research Center of Post-Mining is rethinking water management in the Ruhr area

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 ...

Mining Area Agreement (BBFV) RUHR – Study Regarding the Effectiveness of a New Form of Cooperation

The mining industry of the past has left long-lasting tracks in the territorial structure of the Ruhr area. Dealing responsibly with the area’s mining heritage in terms of sustainable regional developments is a major challenge. In 2014, the 17 pertinent municipalities and districts, together with the state government of North-Rhine Westphalia, RAG Aktiengesellschaft and the Ruhr Regional Association (RVR), concluded ...

Research Center of Post-Mining of the THGA examines microshocks in former mining areas

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 ...
