Tracking down mining with high-tech: “NACHBergbauzeit in NRW” symposium at the THGA

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 ...

Control flight on the coking plant: Research Center of Post-Mining sends drones to search for damage

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 ...

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 ...

First anniversary: Research Centre of Post-Mining of the THGA turns five – and is becoming increasingly complex

The history of mining is long – but the history of post-mining will be much longer. For five years now the Research Center of Post-Mining (FZN) at the TH Georg Agricola University (THGA) in Bochum/Germany has been attending to the issues that emerge as mining activity ceases. As the world’s first institution, it takes a comprehensive look at the post-mining ...
