Radon in the Field of Construction and Regulations governing Radiation Protection

The EURATOM Council Directive 2013/59 dated December 5, 2013 committed the EU member states to implement the principles on radiation protection contained in it, within their national law by 2018. It particularly applied to radon. This article explains why geotechnical engineers must also be involved with the ins and outs of radon, the legal situation and practical applications.

Geosynthetics in Traffic Infrastructure Construction in Contact with Groundwater and Surface Water – Environmental Aspects

According to the European Construction Products Regulation, environmental protection represents a fundamental requirement with regard to structures. This also applies to assessing the suitability of geosynthetic products, which are used for transportation routes, e.g. federal waterways, that have contact with soil and water. This report deals with the regulatory situation and tests relating to leaching behaviour and abrasion. The focus is also on averting microplastics.

Automation and Digitalisation of chemical Grouting to seal anhydrite-bearing Rock

In the new Stuttgart 21 rail construction project, injections to seal anhydrite-bearing rock had to be carried out in the Feuerbach Tunnel. This article explains the further development of the equipment and control technology and the innovative data management system to digitalise and automate the grouting work.

Numerical Simulation to predict Settlements from the mechanised Drive for a Baggage Conveyor System at Frankfurt Airport

A tunnel for a baggage conveyor system (GFA) is being built beneath the two runways for take-offs and landings at Germany’s largest airport. It will be 1.6 km long with a diameter of 8.6 m. The following article explains numerical simulations based on a three-dimensional model, devised to predict settlements resulting from the mechanised tunnel drive involving particular challenges.

New Requirements for Mining Industry due to stricter Occupational Exposure Limits

The K+S Group finds itself facing major challenges since it was decided to introduce new occupational exposure limits (OEL) for nitrogen oxides in Germany. Moreover, the OEL for carbon monoxide and diesel particulate matter (DPM) will also be lowered to comply with new regulations from the Legal Body. The present article describes the efforts and a series of measures undertaken to comply with these stricter stipulations in the near future.

Digital Shaft Hoisting Technology – Increasing Productivity by Avoiding Standstills

It is of great importance for underground mining and tunnelling that shaft hoisting technology is readily available on a reliable basis. The Siemag Tecbert Group thus makes use of digital process and measuring data to provide an extended range of services for the machines and systems it supplies. In this way, standstills are to be avoided, maintenance managed efficiently and productivity increased.

Rockfall Barriers for Kanmantoo Copper Mine in Australia

The Kanmantoo Copper Mine in South Australia was reopened in 2011. Since then Geobrugg has supported the operator by designing and supplying a range of rockfall protection systems for the steep walls.
