Challenges Vertical String Konrad 2 Shaft
The Konrad mine is the first final repository for low- and intermediate-level radioactive waste in Germany approved under nuclear law. The approval process started in 1982 and the approval finally became legally binding in 2007. Due to the requirements of the approval situation and the requirement to build according to…

Industrial Prospects of Marble Quarry Waste: an Analysis of Calcium-Carbonate Applications (Shayan Quarry, Fars Province (Iran))
The Shayan marble quarry in the Fars province (Iran) produces high-quality dimension stones, i. e. calcite marble blocks, but faces a significant challenge as about 90 % of its extracted material is discarded as waste because of intense tectonic-induced fracturing. Geochemically composed of almost pure calcium-carbonate with only traces of unwanted impurities…

Developments and Challenges in the Field of Digital Maintenance
The ongoing digitalization and automation of maintenance strategies has established itself as a central factor for optimizing operational processes in recent years. Particularly in technically demanding industries such as mining, efficient maintenance is essential to minimize unplanned downtime, high maintenance costs and safety risks (1). Author/Autorin: Christel Füllenbach M. Sc., Epiroc Deutschland…

Kinematics Test with a Cutter Wheel Quick-Change System
In addition to the utilisation of terrestrial deposits, maritime ore deposits can also be explored to secure the supply of raw materials, especially copper. Massive sulphide deposits in the deep sea can make a significant contribution (1), if there is a way to extract these ores economically and safely. The…

Mining 4.0, AI and Law
Artificial intelligence (AI) becomes more and more important in smart mining – like in the European Union. According to its Competition Compass of January 2025, one of the Commission’s priorities is to promote investment in future technologies such as AI. What legal framework is already in place, including for digitalization?…

Condition Analysis of Rigid Guidance Systems Using Inertial Sensors
Shafts are the bottleneck of a mine and are essential for smooth and uninterrupted operations. Therefore, their availability is of central importance. Due to the high stresses placed on shafts and their conveyor systems by high humidity, moisture and the transportation of abrasive mining products, the shaft guide rails in…

Interactive Multi-User Hologram Tables for Practical Knowledge Transfer in Mining and Mineral Resource Sciences
The spatial understanding of complex 3D structures is essential in geosciences and mineral resources engineering, but traditional teaching methods are limited. Multi-user hologram tables enable an immersive learning environment through interactive and collaborative 3D visualisations that allow students to analyse geological structures and mineralogical samples together, annotate and intuitively grasp…

Renewable Energies Instead of Domestic Coal: an Interim Assessment
The planned coal phase-out and the energy transition with their climate policy targets in Germany are linked to the expectation that domestic coal and thus coal mining will be completely replaced by renewable energies. To a considerable extent, this has already happened in this country. However, the consequences for the…

How Can Deep Geothermal Energy Support the Heating Transition in Germany?
Deep geothermal energy, as a reliable and sustainable source of heat, will play a decisive role in the heat transition in Germany. This technology uses the geothermal energy stored in deep geological layers to heat buildings and support industrial processes. In contrast to fossil fuels, geothermal energy is (virtually) emission-free…
