Post Mining

Post-Mining as an Example of Economic Evolution. Explanatory Elements in the Work of Helmut Arndt.

Every mining operation and mine site will, as such, come to an end one day and so will transition to the post-mining era. That is simply part of the economic evolution. As for the post-mining sector, which it has long neglected, conventional economic science still finds it hard to accept realistic explanations of evolutionary developments. And yet productive ideas on ...

Targeting a Low-Carbon Economy Using China as an Example: The Pros & Cons of a Shift from Coal to Renewables

Climate neutrality is a global goal that requires the high integration and use of renewable energies to ensure such a transition. In this regard, China in particular, as the largest mining country in the world, is at the forefront of renewable energy production, both through hard coal and rare earths. The great potential faces crucial negative aspects: The production of ...

Emerging Global Trends in the Extractive Industry – International Potential and Future Roles of Remediation Expertise from Germany

Never in history were more mineral resources extracted than at present. In the past 20 years alone global metal ore extraction doubled. If current growth rates continue, more metals will be mined by 2028 than from the beginning of humankind to 2013. This exploding demand is set to rise even further as fossil-fuel based economies transform into low-carbon societies. Along ...

Suspend Coal Phase-Out – Keep Existing Plants in Operation and Reactivate Available Capacities, Give Transition More Time

While there are no fundamental doubts about the direction of the energy transition in Germany – much less the goal of achieving sustainability – the changes in the general circumstances dictating energy policy that have occurred in 2022 give rise to sound arguments in favour of suspending the coal phase-out agreed in Germany. Current law requires the completion of the ...

Mining Engineering Aspects of Underground Waste Utilisation in Saliferous Formations Based on the Mine GTS Grube Teutschenthal

Backfilling of the cavities created by mineral extraction to support the surrounding rock is understood to be an integral part of mining engineering. In contrast to this, underground waste disposal/utilisation is often referred to as a post-mining use of the mine workings, although it requires the same technology and know-how as extraction mining, however with one small decisive difference – ...

Mine Water Rebound in the Former Hard Coal Mining Area of the Ruhr District – Hydrogeochemical Monitoring for a Sustainable, Ecological and Economical Feasible Post-Mining Approach

Mine water rebound including mine water management and water treatment are key perpetual tasks for the operating mine company RAG Aktiengesellschaft, Essen/Germany, and associated foundation RAG-Stiftung, Essen/Germany, since hard coal mining in the Ruhr District ceased at the end of 2018. The scientific support of the mine water rebound process includes a robust risk management and associated hydrogeochemical monitoring to ...

Intelligent Search Engine Makes Expert Knowledge Usable

Hard coal mining in Germany is history, but the expert knowledge from 150 years should remain. But how can information that is hidden in millions of documents on numerous servers be made efficiently usable? To solve this problem, RAG Aktiengesellschaft, Essen/Germany, relies on technical innovation and artificial intelligence (AI), which unlocks valuable knowledge for employees and makes it easily accessible. ...

Landfill Operations Set to Continue at the Former Vereinigte Ville Opencast Lignite Mine

The now depleted Vereinigte Ville lignite mine south of Cologne/Germany has been used as a landfill facility since the 1970s. Each year the 300 ha site receives some 1.7 Mt of mineral waste of landfill class I, II and III. Approval has now been given for a total disposal volume of around 90 M m3. The facility has a workforce ...

Hyperspectral Sensing to Boost AMD Monitoring in Post-Mining Scenery

The evolving hyperspectral sensors have become a big ally for a large range of applications in remote sensing for the monitoring of a variety of earth ecosystems and processes (natural and anthropogenic). The processes occurring within the mining life cycle are not an exception. Hyperspectral sensors have been widely used in a large number of applications ranging from exploration, operation ...
