Abstract The deposit structure of 20 very small to large avalanches that occurred in the Davos area, eastern Swiss Alps, during winters 2004/05 and 2005/06 was investigated. Snow-cover entrainment was significant in the majority of events and likely to have occurred in all cases. Evidence was found both for plough-like frontal entrainment (especially in wet-snow avalanches) and more gradual erosion along the base of dry-snow avalanches. Several of the dry-snow avalanches, both small and large, showed ...

Abstract The objective of mining is to supply society with mineral and therefore to extract mineral deposits safely and economically, and as completely as possible. As shallow deposits are becoming more and more depleted and as the mineral demand is rising, mining has to advance to greater depths or more challenging mining environments. Operational and technical challenges arise consequently. The different challenges are discussed briefly, and it is shown that in particular the importance of rock ...

Es wird eine Anlage vorgeschlagen, die mittels der schrägen Durchstrahlung mit radioktiven Isotopen neben einer Teufenmessung eine Aussage über das Profilbild liefert. Sie besitzt drei Meβebenen mit einen senkrechten Abstand von 500 mm. Jeder Ebene werden vier Detektoren zugeordnet. Die jeweils dazugehörenden zwei 60Co-Strahlungsquellen befinden sich oberhalb der Meβbenen, die Quellstärken betragen 3 Ci. Detektoren und Strahlungsquellen sind so angeordnet, daβ von oben gesehen ein regelmäβiges Achteck ...
