Worldwide, but particularly in Germany, mining is caught between the conflicting demands of supplying industry and the population with mineral raw materials and ecological and social requirements. How to apply innovative technologies and processes for the sustainable extraction of minerals is therefore one of the greatest challenges facing this branch. Our latest issue of Mining Report Glückauf outlines some of the approaches being adopted in this area. Expansion plans for surface mining projects have increasingly stringent regulatory barriers to overcome …

Applications of Geophysical Measuring Methods for the Exploration and Securing of Old Mine Workings Near the Surface Using the Example of the Former Lignite Mine Robertshall

During the expansion of the Ehestorfer Heuweg road in the village of Ehestorf, district of Rosengarten/Germany, a daybreak occurred on 11th September 2019, which had a diameter of approximately 0.5 m and a depth of approximately 5 m. Research in the archives of the State Office for Mining, Energy and Geology (LBEG) in Clausthal-Zellerfeld revealed that the probable cause of the collapse can be traced back to the former Robertshall lignite mine, which mined lignite underground here and was in operation until 1922. The collapse suggested that the sand backfill introduced into the roadways crossing under the road during the closure of the mine was not sufficiently stable …

WG Heave Phenomena – Insights, Knowledge Transfer, Research Topics, Results

Even before the Act on the Financing of the Phase Out of Subsidised Hard Coal Mining came into force at the end of 2018, the effects of mine flooding on mining damage were increasingly becoming the focus of public attention. In order to pool knowledge on the possible effects of mine flooding on the surface in advance, the working group “Heave phenomena due to mine and groundwater rise” was established on 14th September 2006 by a resolution of the board and the advisory board of the Deutscher Markscheider-Verein e.V.. The working group (www.dmv-ev.de/arbeitskreise/bodenbewegungen.html) is made up of representatives from active mining companies, rehabilitation mining, mining administrations, universities and specific institutions.

This pilot project is based on an initiative being developed by Basalt-Actien-Gesellschaft (Basalt AG) in Linz am Rhein/Germany: While domestic raw materials extraction has for many decades been a cornerstone of the economy and a key factor in the delivery of essential services, rock quarrying today is increasingly caught between the conflicting priorities of industrial production, on one hand, and ecological requirements and social demands, on the other. The ongoing extraction of surface resources is now facing a number of high regulatory barriers. The Großsteinberg open-pit mine, which is owned by the Hartsteinwerke Bayern-Mitteldeutschland, has come up with a solution that is likely to be acceptable to all parties …

Copper ores are found in massive sulphide deposits in the rift zones of the oceans. For the exploration and mining of these hydrothermally formed and very small-scale heterogeneously structured deposits, exact position data of the mining equipment used and also of the individual mining tools are required. At depths of over 2,000 m, navigation has to manage without the support of established navigation systems and is carried out using inertial measurement systems. These must be designed to meet the requirements of the deep-sea environment as well as the extreme vibration stresses from the mining process. The use of robust electronic sensors requires …

BIM – Taking Collaboration in Mining to a New Level

Section through the coordination model in the BIM model viewer. Source: CDM Smith

The engineering industry often faces the challenge of extracting knowledge from a wealth of collected information. Without adequate capture, structuring, maintenance and provision of planning information collected over time, there is a risk that essential project knowledge is lost. Building Information Modeling (BIM) has established itself as a widely proven and established method for efficient collaboration, especially in the field of high-rise and infrastructure construction, where it is now considered standard. BIM is a process-oriented approach that involves the creation and management of digital representations of the physical and functional characteristics of a construction project. It enables the actors to access a common data base through …

According to the 2024 Ernst & Young ranking of top business risk and opportunities in mining and metals, workforce talent recruitment and retention, as well as digital technologies and innovation towards Mining 4.0 remain in the top ten of the outmost challenges for mining. On the first, the industry is conducting several initiatives to address the younger workforce better and to create more attractive workplaces. On the second, not only the industry plays a key role …
