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 ...

Reports on Post-Mining – scientific series from the Research Center of Post-Mining now available online

The Research Center of Post-Mining (FZN) at the TH Georg Agricola University (THGA), Bochum/Germany, has a broad field of focus. When it was established in October 2015, research focused initially on the perpetual tasks of the German coal mining industry: long-term mine water management, the management of polder areas and groundwater purification on former mine sites. In May 2019, the ...

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 ...

Following the coal trail

Construction sites, closures, narrowed lanes: Since the end of March 2020 the patience of drivers who use the Dortmund/Witten motorway junction is being tested. But the remediation work on the A44 is urgently required, says Cedric Kamgaing Kamdom: “ Most recently we detected and backfilled a hollow space, which was around 10 m high and 3 m wide – roughly as ...

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 ...
