The Future of Mining in the 21st Century

Bernd G. Lottermoser

Future mining has to face major challenges and needs to embrace five revolutions – the social, energy, environmental, education as well as technology revolution.

Foundation Piling for the New Champlain Bridge Corridor Project in Canada

Amr Aly and Nick Papas

The new Champlain Bridge in Montreal, Canada, is one of the largest infrastructure projects in Eastern Canada. Bauer’s scope was 200 concrete piles – 190 piles drilled from land or jetties and 10 marine piles drilled offshore from a barge in the St. Lawrence. The project team had to meet the aggressive schedule, adverse weather conditions and strict safety, quality and environmental challenges.

Design Method for structional Fire Protection in Traffic Tunnels using a Mining Construction Method

Carsten Peter

The theoretical verification of a fire incident for tunnel structures using the Advanced Calculation Method of the DIN EN 1992-1-2 involves a complex procedure. The results obtained from two representative tunnel cross-sections are presented. In the process, the application of PP fibre concrete is taken into consideration as a structural protection measure.

Gaskets for Sealing Segments in the Boßler Tunnel and innovative Developments

Christian Braun

The Datwyler Group is constantly advancing the development of sealing systems for segmental tunnels. To this end, it makes use of the experience gained from some 650 tunnel projects worldwide. This article examines innovative developments for overcoming tricky, ever-changing geological marginal conditions and for enhancing efficiency during installation. Examples of projects – especially the Boßler Tunnel – serve to clarify practical use.

Criterion for Predicting the Risk of a Gripper TBM Jamming

Jürgen Schmitt, Omid Monfaredpur, Ulrich Burbaum and Rohola Hasanpour

Jamming or blocking of the cutter head of a tunnel boring machine (TBM) represents a high risk for a tunnel excavation. Extensive investigations have been carried out for tunnel boring machines with shield and double-shield machines and criteria devised for design and dimensioning purposes. These approaches cannot be transposed to tunnelling with a Gripper TBM as the stress deformation behaviour of the rock differs. This article examines three-dimensional numerical parameter studies for analysing the stress deformation behaviour of the rock for excavations using a Gripper TBM and diagrams subsequently derived from them for estimating the risk of a Gripper TBM jamming.

In-situ Bioextraction of Industry Metals from deep Ore Deposits to secure EU Resource Supply

Romy Matthies, Horst Hejny, Knut Hirsch, René Kahnt, Horst Märten and David Barrie Johnson

The Biomore research programme brings together 22 European and non-European partners from industry and research. The project aims at developing an environmentally-friendly method for the extraction of technology metals from poorly accessible, i. e. deep ore deposits. To this end, the metals are extracted by combining deep drilling, fracturing and in-situ bioleaching. The pregnant leach solution is further processed at the surface. GeoResources interviewed the project manager on important aspects of the project.

No nuclear Power – no Disposal Facility?

Jörg Feinhals, Duncan Kemp and Anastasia Savidou

Even if countries have no nuclear power programme they often produce radioactive waste,  e. g. from medical, industrial and research facilities, and have to responsibly deal with low amounts of the waste. This article discusses the challenge and different concepts for safe and affordable disposal solutions.
