On the Potential and Sustainability of water-based Hydraulics

The corona crisis and climate change have created a new set of challenges. Political support for economic activity, both in Germany and in the EU in general, is now quite deliberately focussed on climate and environmental protection. Water-based hydraulics have a contribution to make towards the implementation of these policy objectives.

Pit Thermal Energy Storages (PTES) with innovative Sealing for a successful Energy Turnaround

The use of renewable energies and a successful energy turnaround require suitable storage facilities to compensate for time differences between the generation and the use of energy. Pit Thermal Energy Storages are a proven solution for district heating. Their sealing poses particular challenges, and these are explained in this article.

‘Green’ Hydrogen Production on a commercial Scale with Underground Storage and Heat Extraction

Hydrogen from renewable energy sources will in future be produced by electrolysis on a commercial scale and stockpiled for energy storage purposes. This paper discusses the cost and efficiency aspects of the production and underground storage processes.

Archaeological Study on Reinforced Soil for Hydraulic Engineering in ancient China

Based on detailed historical data, the application history of reinforced soil in hydraulic engineering in China is studied. Archaeological research shows that ‘grass wrapped sludge’ technique was invented in ancient China about 5,000 years ago and the technique was widely used in dam construction for flood control, river regulation and breach blocking. Geosynthetic reinforcement and protection techniques were introduced to China only in the 1960s to 1970s, while the application of reinforced soil in hydraulic engineering has a much longer history. Geosynthetics reinforcement is inheritance and development of ancient wisdom for modern civilisation.

Swiss Tunnel Congress 2020 goes digital

For the first time in its long history this year’s Swiss Tunnel Congress (STC) was arranged as a webinar event due to the corona pandemic. The organisers successfully mastered the challenges posed by the new format and the congress and colloquium provided participants with a wide range of high-calibre presentations.

The GeoResources Team in an interview with Dieter Mantwill

Eco-friendly hydraulic Fluid offers real Versatility

Environment-friendly hydraulic fluid, as developed over the course of three decades and already well proven in the German coal industry, offers versatile potential for use in a wide range of applications. The GeoResources Team interviewed Dieter Mantwill, the managing partner of Fluid-Competence GmbH, on the relevant prospects and opportunities.

Flow Simulation boosts Efficiency in the Salt and Potash Industry

The salt and potash industry has not been dragging its heels when it comes to the ongoing improvement of mining and production techniques – with the solution mining process used at the Bethune mine in Canada being a case in point. Modern software tools offer efficient numerical methods for flow simulation that can identify and develop optimisation potential, boost efficiency and help introduce innovative operational procedures. The result can be higher product quality, improved customer satisfaction and the added benefit of lower costs.

Consolidation of Fracture Zones in the Russian Ore Mining Industry

Geological fault zones in a number of non-ferrous metal ore mines in Russia have caused roof falls and roadway collapses that have severely hampered roadway drivage operations, affected mine ventilation systems and compromised worker safety. Injection bolts have proved to be a cost-effective solution to these recurring problems.
