Assessment of Working Conditions at Mining-Metallurgical Enterprises

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 ...

Detection and Differentiation of Sand Content in Hydraulic Transport using Acoustic Emission Technology

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 “Vertical Approach” – a Sustainable Solution for Deep-Sea Mining and Sampling

The discovery of Seafloor Massive Sulfides (SMS) occurred in the Galapagos Rift area in 1977. A few years later, the former German mining company PREUSSAG AG started with the exploration of these newly discovered mineral resources followed by a first harvesting campaign of 30 t of massive sulfides collected with big TV-controlled grabs. In contrast to conventional mining concepts the ...
