Focus on the Future, or ’suppose that’

Katrin Brummermann

’Suppose that’ our mind games about the future of what we do in the areas of geotechnical engineering, tunnelling, mining and raw materials positively influence the decisions we take today. Then the special topic “Focus on Future” in this issue should have a lot to offer.

Climate Protection and Sustainability – a personal Issue and a Challenge for the Geotechnics Branch

Antje Müller-Kirchenbauer

Climate protection and sustainability affect us all – both on a personal level and at our place of work, and the DGGT (German Geotechnical Society) is no exception to this. So let us do our bit by rising to the challenge and making an effective contribution.

Erosion-stable Road Embankments – Design and Selection of System Solutions

Anabell Klein

Temporary or permanent erosion-control measures on slopes along roads contribute to traffic safety and climate protection. This article deals with the mechanisms of slope erosion, the selection of suitable protection solutions, and their design.

Shore Protection against Erosion: Carbon Footprint of an innovative Steel Wire Mesh Cell Solution compared with other Solutions

Matthias Denk

Geobrugg developed an innovative solution of steel mesh cells in high-tensile stainless steel for coastal protection. This article estimates the carbon footprint compared with rock armour and concrete revetments for a case study in Devon, United Kingdom.

A firm Hold for Infrastructure Project ‘Le Grand Paris Express’ – Fixing Systems ­secure Metro Lines 15 and 16

Fischer Group

The major project, the ‘Grand Paris Express’ contributes to the future development of Paris and will double the length of the Parisian metro network by 2030. The ‘Grand Paris Express’ will add lines over 200 km of new tracks as well as 68 new stations. Fischer injection mortar is used for line 16 to connect the floor slabs to the retaining walls.  For ring line 15 fixing systems are used to fasten anchor cable runs in concrete.

World’s first Deployment of a full-face Tunnelling Machine with Mineral oil-free Hydraulics

Michele Rossi

A full-face tunnelling machine running on biodegradable hydraulic fluid has now been used to drive a steeply inclined tunnel in a water conservation area. This article reports on the project and relates the experience acquired with this new type of hydraulic fluid.

Auxiliary Ventilation for dust-intensive Working Environments

Jens Kegenhoff

All kinds of technical correlations and parameters have to be taken into account when designing professional cleaning systems for dust-laden air. In order to filter the dust load from the air the latter has to be set in motion by means of fans so that it can pass through the filter system. For mechanised and conventional tunnelling operations the air circulation and dedusting regimes have to be properly coordinated with each other. Auxiliary ventilation systems have to take many different parameters and relationships into account if they are to achieve effective dust removal and air cleaning results.

Evaluation of the Use of field-portable LIBS Analysers for on-site chemical Analysis in the Mineral Resources Sector

Nils Schlatter, Guillaume Freutel and Bernd G. Lottermoser

Portable laser induced breakdown spectroscopy (pLIBS) is an analytical method for determining the elemental composition of solid material surfaces. Field-portable devices are gaining increasing acceptance in the mineral resources sector, offering rapid, on-site chemical analysis.

Preparing the German Konrad Repository – Digitisation of Installations, Systems and associated Components

André Fries and Volkmar Riedel

The Konrad permanent waste disposal facility in Germany was given final approval in 2002. The original concept for the manual documentation of all installations, systems and components (ISC), which is an essential part of the verification requirements, has now been made much more efficient by using digital technology.

16th international MiningForum shows best Practices for a sustainable Future in the natural Resources Sector

DMT GmbH & Co. KG

‘For a Sustainable Future’ was the motto of the international 16th MiningForum and the exhibition hosted by DMT Group in Berlin on 19 and 20 May. The event offered a 360-degree perspective on all relevant areas of the natural resources sector and was once again held under the patronage of the German Ministry of Economic Affairs and Climate Action (BMWK).

Preserving the cultural and industrial Heritage of Mining Regions as a social Component of Post-mining Era

Hennadii Haiko and Natalia Lubenska

The cultural and social aspect of post-mining is considered as an important component of the transition process under way in coalfield regions. This paper describes international experience in preserving the cultural and industrial heritage of the mining industry in regions in transition and seeks to identify those coalfield regions of Ukraine that have significant potential for mining museumification. It goes on to describe the challenges of creating a scientific methodology and the professional tools that are needed for preserving the cultural and industrial heritage of 20th and 21st century mining industries and analyses the feasibility of financing projects for establishing a dedicated mining museum.
