"Airlift" facility: TU Freiberg tests new mining technology in research and training mine

22.10.2019

At the TU Bergakademie Freiberg, research is carried out into the preservation of the foundations of life in our society. Above all, this includes the secure and environmentally friendly supply of energy and raw materials. With the "Airlift" facility inaugurated on 22 October, scientists from the TU Bergakademie Freiberg and Polen are testing safe and clean technologies for the extraction of raw materials using high-pressure water jets. The results will flow into the construction of a pilot plant close to industry.

On the new six-metre-high test rig, researchers at the Technische Universiät Bergakademie Freiberg are testing the transport of the crushed material to the surface via a borehole.

The material is sucked out of a closed cavern (underground cavity) and crushed with the aid of compressed air and water and transported to the surface.

"The intervention at the surface is minimal. The resulting cavities are later filled again. Nobody has to go underground," explains Prof. Drebenstedt.

The Freiberg scientists are now investigating the optimum operating parameters for the new borehole technology in a practical manner in the new "Airlift" facility in the university's own research and training mine "Reiche Zeche".

The results should provide information about the operating conditions, performance and costs of the plant, which will be built in 2020 as an industrial pilot plant in Katowice, Poland.

The process can be used to extract various raw materials. Initial experience has been gained with uranium, phosphate and coal.

The research work is part of the research project "HydroCoal Plus" funded by the European Union within the framework of "HORIZON 2020 / 7th Research Framework Programme" and will be carried out together with Polish and Czech experts.

Im Focus: Junior scientists at the University of Rostock invent a funnel for light

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.

The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.

Im Focus: Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.

Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
