Glückauf! 2/2023

The political decisions that have been taken to transform Germany’s energy production system envisage a departure from fossil resources and the accelerated application of renewable energies and e-mobility. This not only involves the new and recognised concepts for electricity generation and transmission but also includes energy storage and associated issues relating to the sourcing of the minerals that will be required. Take the rare-earth elements, cobalt, magnesium, lithium, copper and other materials, for example: Last year more than 90 % of the metal resources we use in Germany were imported from abroad …

Historic Mining Infrastructure as an Opportunity for Regional Water- and Energy Supply: The Water Reservoir Harz 2050 Project

Overview of the aspects of WSH 2050 as a holistic model of the water management region of the Harz. Source: TUC

High precipitation, dams and waterworks make the Harz Mountains a large freshwater supplier. But, challenges arise based on climate change and extreme weather events. Old mine working can support water management if integrated into the system. Successful planning and integration need a holistic understanding of the regional water cycle, the current situation of the mine workings and the interaction. The development of a hydro-analytical water management tool establishes a link to analyse excavation utilisation enabling …

Digital Twin – Integrated Geomonitoring

Methods used for geotechnical and environmental monitoring. Source: https://doi.org/10.1127/zdgg/2022/0335

One of the main challenges facing us today is the environment and how to protect it. Mining activities over the years have had an enormous impact on the three environmental elements water, soil and air. Ground movements in mining areas can be observed both during the mineral winning phase and after this has ended. This phenomenon may affect the water balance of a region as a rise in the groundwater level can lead to “water stress” in plants, which in turn can manifest itself in reduced vitality …

Restructuring of the Coal Industry in Ukraine

The structure associated with the liquidation of the mine. Source: Authors

Ukraine ranks 7th place in the world in terms of coal reserves. On the territory of Ukraine there are three coal basins: Donetsk, Lviv-Volyn and Dnipro, the largest of which is the Donetsk basin, where 85 % of Ukraine’s coal resources are concentrated. Since the mid of the 1990s the coal industry of Ukraine is being restructured, the purpose of which was to abandon state subsidies for unprofitable mines, with their subsequent closure and the privatization of profitable or potentially profitable mines. Despite the fact that Russia’s aggression against Ukraine has made its own adjustments to the work of coal enterprises …

Rare earths, cobalt, magnesium, lithium: Over 90 % of the metallic raw materials used in Germany were imported last year. A significant part of these imports originated from countries with difficult political situations or monopolies in the exploitation and processing of raw materials. These dependencies have gained even more geopolitical importance against the background of the Russian aggressive war against Ukraine. Given the expected growing demand for critical raw materials …

As global powers work to secure mineral supply chains for high-capacity battery manufacturing, collaboration with Africa is more important than ever. Germany’s participation in the Minerals Security Partnership (MSP), an alliance of twelve nations and the EU, signals that winning the race to secure battery minerals requires global collaboration. The MSP engages African partners, including the stable, democratic, resource-rich and under explored East African nation of Tanzania …

Peru is considered one of the ten richest countries in resources in the world and currently occupies an important place in the production ranking. The country is home to numerous mining companies that are increasingly focused on the innovation of technologies and processes, which has improved the competitiveness of the industry. The objectives in Peruvian mining in this development are to increase efficiency in production, in the use of energy and other resources, as well as to increase occupational safety, reduce costs and prevent accidents. To ensure the long-term competitiveness …

Exploration Concept and Implementation of a Salar with Lithium Brine in South America

Example for exploration well design with additional connecting geophysical explo­ration program. Source: K-UTEC

Salars and salt lakes occur in South America and other arid areas of the World and contain large quantities of lithium brine. The concentration of brine varies across the salars. A good knowledge of the internal structure of the salars is needed to optimize the exploitation and pumping plan. This information is also needed to ensure that brine production is done in an ecologically sustainable way.

The Introduction of Battery-Electric Mining Equipment – Opportunities and Risks

Top risks for the mining industry. Source: KPMG (2022): Global Mining Outlook 2022

The requirements for the realization of greenfield projects have changed due to the aspiration of society, but also of potential investors, for sustainable raw material extraction. Through emission-free mining technology, the expectations of the industry can be met more and more. In the future, the success and support of greenfield projects will increasingly depend on what sustainability goals are set and how conscientiously work is done to achieve them. Early and close cooperation between the operator and the machine manufacturer will be a decisive prerequisite for the success of a project …

The exploration of space has fascinated humankind for decades. Along with this, establishing a colony on other celestial bodies, such as the moon or Mars, has gained increasing interest. For building such a colony, the use of extraterrestrial raw materials is of great importance. In order to make these raw materials usable, just as in terrestrial processes, the first tasks are prospecting for valuable resources as well as mining the mineral raw material. Due to the challenging environment, innovative and highly autonomous processes are required for the excavation of raw materials …
