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…

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…

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…

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…
