Wirtgen Drives the Development of Surface Mining

open access: yesProcedia Engineering, 2016
AbstractWhy not to apply know-how gained in asphalt milling to the mining of hard rock? In the mid 70s, this idea triggered the development of a new, economically efficient opencast mining method known as Surface Miner Technology. What followed was an unparalleled success story, and it was headed by Wirtgen as the driving force behind it right from the

Modeling Vacuum Arcs [PDF]

open access: yes, 2010
We are developing a model of vacuum arcs. This model assumes that arcs develop as a result of mechanical failure of the surface due to Coulomb explosions, followed by ionization of fragments by field emission and the development of a small, dense plasma ...
