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.
The CFH Group – Pooling technical Know-how and Reinforcing its global Presence with an expanding Range of Services
Operating from its Gladbeck HQ the CFH group of companies continues to pursue an active development path even in these crisis-hit times, pooling its technical expertise in air technology, working towards a stronger global presence and expanding its service portfolio.
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.
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.
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.
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.
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.
The Siemag Tecberg Group has developed a bulk materials handling system that can efficiently transfer the direction of flow from horizontal to vertical. This article examines the benefits of the system.
After many years without any significant developments in transport technology the deep mining industry is now signalling a new mood of invigoration in the market for mobile loaders and haulage equipment. Electric-drive vehicles are now suddenly gaining ready acceptance in this sector.
Rescue Vehicle for long-distance Emergency Missions in Mines and Tunnels – a field-proven tactical Resource for Underground Safety
The MRV9000 rescue vehicle was designed for use in underground mines and tunnels where long travelling distances are involved. Developed jointly by Paus and Dräger this specialised vehicle provides greater transport safety for recovered persons and rescue teams and has already proven itself in the field over several years.
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.
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.

Das Buch 3 der Reihe „Dokumentation der technischen Entwicklung bei der RAG“ stellt die Evolution der Vorleistung in den vergangenen 50 Jahren dar. Da sie den Zugang zur Lagerstätte schafft, ist sie die Grundvoraussetzung zur Gewinnung des Rohstoffs Kohle und bildet die Grundlage für den langfristig sicheren und leistungsfähigen Betrieb eines Bergwerks.
