It was not only hard coal that was mined in Germany for several hundred years. Other raw materials of stone and earth, such as ore and salt, have also been mined in Germany for a long time. At many mining sites, we have now entered the post-mining era.
In today's densely populated mining regions, legacies from former mining times pose serious civil risks and subsoil risks. These include, in particular, inadequately secured former mining zones, openings that have not been preserved in accordance with the current state of the art, such as shafts or tunnel mouth holes and abandoned open-cast mines.

Due to increasingly dense settlement and post-daily land use, additional issues arise, such as the stability of mine workings, open pits or shafts, as well as the regulation of mine water or outgassing situations, for which sustainable, economic and ecological technical solutions must be found.

These must not only be taken into account in the planning and development of new construction projects, but can also pose a considerable risk potential for existing structures, open spaces and traffic routes.

Not only the direct effects of mining activities mentioned above, but also the peripheral phenomena such as dumps, waste rock piles, sludge ponds, clarification and sedimentation basins are now part of the mining legacy that must be considered in a sustainable subsequent use of the land.

We are accredited by the mining authority of North Rhine-Westphalia as publicly appointed and sworn experts for old mining (Dr.-Ing. Scherbeck, Dipl-Geol. Stempelmann).

We offer expert support, planning services and advice on the following typical topics:
