When we think of natural resources, most people think of coal, oil and gas, iron ore, copper and gold. Public perception is dominated by their importance in areas such as energy production, steel production and infrastructure – and traditionally, the commodities sector is associated primarily with the extraction of fossil fuels. This is one of the reasons the entire sector ...

In this paper, a comprehensive assessment of the psycho-physiological state of coke production workers within real production scenarios regarding mining enterprises was completed. The objects of research have been workers of the coke-chemical production ArcelorMittal Temirtau in Kazakhstan. To define preventive measures, the criteria to identify risk groups and loss of efficiency were calculated and a prediction model for the ...

In a world with a growing population the need to achieve climate policy goals as well as the UN sustainable development goals, primary mining for raw materials will continue in the coming decades. In the long term, recycling of metal stocks and a circular economy represent the most promising and responsible solutions and will help to eliminate the environmental and ...

Deep-sea mining represents an opportunity for an alternative supply of high-tech raw materials. A concept for the extraction of polymetallic nodules from the seabed envisages the use of a harvester that extracts the nodules using a hydraulic principle. To design an effective and efficient mining process, the composition of the material flows must be continuously monitored. A promising technology for ...

The Research Center of Post-Mining (FZN) at the TH Georg Agricola University (THGA) in Bochum/Germany has significantly expanded the range of its research programme since 2019/2020. Its scope has now been broadened by the new research division “Reactivation and Transition”. Research in this division focuses on land development and regional policy, socio-economic aspects and governance of post-mining. Emphasis is less ...

In recent years and decades, structural change has taken place in all German mining regions. In general, it can be said that the old-established, large-scale coal and ore mines have been closed down or have moved from an active extraction phase to rehabilitation mining, combined with a corresponding reduction in the number of employees. At the same time, we are ...

afety is the highest goal in a mining operation due to its responsibility towards the involved persons as employees but also in terms of the society. Furthermore, economical risks are closely related to unsafe working standards enhancing the severity of incidents. The mentality for safe and aware behavior needs to be set for all internal stakeholders of mining activities and ...

Due to the recent announcement by the Chinese President Xi Jinping to become carbon neutral by 2060, China is facing a major upheaval. Because in China, power generation is the largest consumer of coal and remains a major future source of energy. In the upcoming age of renewable energies and climate protection, the transition to a more sustainable energy supply ...

The decision to phase out coal in Germany – and not only there –with the corresponding loss of added value and jobs in coal production and use raises the question of how sufficient new employment stimuli can be created for the regions of the coal industry in the post-coal-mining era. The federal government’s answer is the billions set aside by the ...

In practice bulk material transfer chutes for belt conveyors often cause problems. Depending on the bulk material to be conveyed, the chutes are often subject to severe wear, which minimizes the durability of the chutes and expensive wear protection material is often replaced at very short intervals. The wear also relates to the belt conveyor downstream of the chute. If ...
