The former Teutschenthal potash mine, with mine sections Teutschenthal, Angersdorf and Salzmünde, is currently operated as a backfilling mine by GTS Grube Teutschenthal Sicherungs GmbH & Co. KG (GTS). In accordance with the Ordinance on Underground Waste Stowage (VersatzV, 2002), the four shafts connected to the mine, as elements traversing geological barriers, must be sealed off for long-term safety at ...

ECOSOIL Nord-West GmbH, Bochum/Germany, is carrying out a shaft renovation using a cohesive partial filling column, including dismantling and refilling of the “Vondern 1 and 2” double shaft system together with a ventilation duct on behalf of the steel division of thyssenkrupp. The plant belongs to the former Vondern mine (a hard coal mine from 1902 to 1932) and is ...

This study describes the options of science communication based on experiences of the German foundation “Forum Mining and Water”. After the cessation of German hard coal mining, the foundation aims to address the topic of mine water and mine flooding. Since its establishment in 2017, various communication formats have been employed by the foundation to disseminate its research findings and ...

Against the backdrop of diverse and overlapping transformations in Germany, such as the energy transition, electromobility, digitalization, climate change and the green transformation as a whole, secure access to high-tech raw materials is of central importance. It is also important to maintain the innovative strength and competitiveness of German industry and to upgrade the infrastructure for the future. In the ...

Mongolia has occupied a key position in the global mining sector. The country is one of the ten most resource-rich countries in the world. In the south of the country, which has a very sparsely populated population of around 3.4 million, in the Gobi Desert, there are gigantic deposits of copper, silver, gold, coal, fluorspar and other raw materials that ...

Mauritania is rich in raw materials. Gold, iron ore or copper are mined on an industrial, modern scale. Oil and natural gas are also produced. Artisan mining takes place on gold, rock salt or gypsum. In addition to other raw materials, the Mauritanian part of the phosphate deposit already used in Senegal or the Terechrecht rare earth deposit southeast of ...

The world’s energy supply is changing – from the direct use of fossil fuels to generate electricity, to so-called renewable energies. Furthermore, the expansion of e-mobility and increased demand for information technology require additional grid and generation capacities. Copper, which is essential for all power supply systems and grids, plays a central role. The rapidly increasing demand for copper is ...

In spring 2024, the International Energy Agency (IEA) presented a new special report on the international coal sector. This is addressed to the global community. However, the IEA’s well-founded recommendations also allow energy policy conclusions to be drawn for the phase-out of coal-fired power generation that has been decided on, planned and launched in Germany. This is by no means ...

The IAW33 research project “Innovative processing technologies and their potential for the recovery of recyclable materials from mine water, precipitates and tailings from the Ruhr, Saar and Ibbenbüren areas with special focus on critical metal resources”, which the Research Center of Post-Mining (FZN) at the TH Georg Agricola University (THGA), Bochum/Germany, launched in 2022, has been engaged in investigating the ...

Modern society relies on mining and quarrying to secure a steady supply of mineral resources supporting technological advancements and elevated living standards. Products of mining are crucial for various technologies, while waste, in the form of tailings, poses considerable environmental risks. This review explores the dual nature of mine tailings, examining both their adverse environmental impacts and their potential for ...
