Adapting Water Management to Climate Change – a technical and social Challenge
Adapting water management to climate change is a major challenge that must begin today. It will comprehensively occupy coming generations and it requires innovative technical, economic, social, and environmentally compatible measures and solutions.

Commercial Scale Carbon Dioxide Capture for the Storage in the deep Underground and Enhanced Oil Recovery (EOR)
Carbon dioxide from industrial flue gases associated with steel making, cement production and the chemical industry can be separated out and stored in deep geological formations. This article discusses the potential processes and their associated costs.

Rockfall Tests under realistic Conditions in the Swiss Alps
In 2019 and 2020, the WSL Institute for Snow and Avalanche Research SLF and Geobrugg AG conducted tests at the Flüela Pass to investigate the effects of realistic impacts of test blocks on rockfall barriers.

Driving a DN 2600 Microtunnel under an active Rail Track: the Leither Bach Qmax Link Project
The redevelopment of the Emscher river system in Essen, Germany, called for a microtunnel to be driven beneath a Deutsche Bahn line. This paper outlines the planning and internal approval processes associated with the operation, which involved tunnelling beneath an active rail track, and describes the monitoring technology that was the key to the successful completion of the Leither Bach Qmax link project.

0G network-based Digitisation for Monitoring post-closure Mine Entrances and other Applications
The old mining shafts are abandoned now – but not forgotten. In fact quite the reverse, for they still have to be monitored on a regular basis. This is a time consuming and costly business. The solution: digitise the monitoring regime. The Sigfox 0G network is now able to connect things to the internet in a way that would have been impossible before because the process was either too energy intensive or too expensive. Other underground applications have already been put into practice, including systems for the Antwerp water supply network in Belgium and for the logistics services at a tunnel construction site.

In-situ Detection of loose Rock
Any successful performing scaling depends on the accurate identification of loose rock. The Scale Sense project aims to integrate sensors into a scaling machine in order to assist the equipment operator with this task. This will contribute making scaling a safer and more efficient process.

Mine Water Rebound in a Post-closure Environment – Background and practical Experiences
The closure of collieries is followed by a post-mining phase that is usually characterised by rising mine water levels. In Europe the coal mining industry has been undergoing structural change for many years and this process continues to this day. This paper presents some of the experiences acquired by the THGA in producing a research project on mine water rebounds in the European coalfield regions whose findings will serve as a reference for future measures aimed at long-term, environmentally sustainable groundwater management.

Contribution to the selective Extraction of Lignite from historical Seam Workings
Major attention is now being focused on the opencast extraction of lignite deposits in the central European region, where large amounts of brown coal were left virgin by the underground mining operations of the 19th and 20th century. Analyses carried out at German and Czech opencast lignite mines have now produced a set of recommendations for special technologies for caved gob zones that would facilitate the extraction of lignite from historical seam operations. Advice was also provided on dealing with the legacies of the underground mining industry and on planning effective site remediation measures.
