Geotechnics
New Diaphragm Cut-off Wall for the Rosshaupten Dam
The Bavarian Rosshaupten Dam was modernised. A diaphragm cut-off wall was built as a new sealing element in the existing dam. The difficult construction tasks could be solved using modern machinery and measurement technology.

Eyelet Gabion System with National Technical Approval
Gabion structures are becoming ever more popular in practice for retaining purposes. The Hoy Geokunststoffe GmbH has further developed its gabion system Quicky Forte 2000. As a result, it has received a National Technical Approval (abZ) from Deutsches Institut für Bautechnik (DIBt). This article deals with the development work that has been tackled as well as tests and verifications attaining during the approval procedure.

The Mine of the Future: The 5S Innovation Model for the Minerals Industry
This article introduces an innovation model based on defining ultimate operational conditions that the mining industry will face in the near future. The model is designed to be adaptable to any type of mining. Five innovation drivers are defined that are essential to stay competitive during the decades ahead. The model can serve as a road map to develop technologies and methods for the “mine of the future”.

The changing Salt Mining
The Südwestdeutsche Salzwerke AG mines and produces rock salt and evaporated salt. Conventional drill+blast was used to mine the salt for all of 120 years. Since 2006, continuous mining using Continuous Miners has taken over. Conventional methods are now only applied to cope with peaks when demand fluctuates.

The Potential for Development of Underwater Natural Gas Storage in Europe
Underground gas storage (UGS) facilities cannot be located in all European gas-consuming countries due to unsuitable geological conditions. Underwater gas storage in impermeable spheres could provide an alternative solution. This article explains the UGS situation in Europe and an unimplemented underwater project idea in Russia.
