Legacies of abandoned underground mines

We dig deep for you 

More than 60,000 old mine shafts and galleries in the German state of North Rhine-Westphalia alone show how strongly mining has shaped the historical development. Industrialization and the associated population growth have led to a strong expansion of the infrastructure and heavy mining exploitation of the deposits. Particularly in the southern Ruhr area, this expansion affected areas where hard-coal was mined close to the surface. As a result of this development, the infrastructure has been endangered due to the instability of abandoned mines.

For decades many authorities, legal successors to the mining companies or affected businesses have relied on DMT's performance to evaluate and secure mining legacies.

Our engineers provide support, expert opinions and advice on issues relating to old mines. We develop concepts that permanently restore the integrity of the surface. We work on an interdisciplinary basis with our teams and analyse the situation on site from a geotechnical and mining point of view. We react immediately and support our clients in further measures in the handling of damage events.
