Fully Automated Underground Mine
Since its mechanisation – mainly 1950s to 1970s – and first approaches for automation of single processes – since late 1980s – the mining industry is now developing solutions for complete automation systems for independent mine sections or, ideally, entire mines. Applications will be found first in countries of intensive mining…

Selective Excavation of Spoil Dumps Using Heavy Machinery: Study Based on a Chilean Tailings Impoundment
Mine tailings are often disposed of in slurry dumps. Older facilities of this kind may include relating dams that have been poorly designed and constructed. This can pose a threat to local residents and the environment. Progressive oxidation can result in the dissolution of metals. This may impose an increased…

A First Step Towards Landfill Mining
The term “urban mining”, which is now a well-known concept, refers to the reclamation of compounds and elements from man-made sources. When buildings are being demolished, e. g., any valuable materials encountered, such as copper pipes and cables or old lead piping, can be extracted separately and the metals reused. Concrete…

Acoustic Emission Technology and Thermal Imaging for Material Flow Characterization in Mining
Successful process control during the extraction process, as well as the enrichment process of primary raw materials, requires the sensor-based determination of the material composition. Typical technologies, which have been utilized successfully in the mining industry, make use of the electromagnetic spectrum, e. g. XRF, LIBS, NIR, etc. These technologies are…
