The effort with which the LMBV (our client) is advancing the design and protection of the post-mining landscape in Central Germany is exemplified by the high professional and technical level.

The collected contributions summarise the measures taken to cope with the 2009 embankment event. This project was unique for all involved and is unsurpassed in its complexity.

M&P Group employees are proud to have been involved in the management of the 2009 embankment event.

The successful planning and implementation of the project required effective cooperation and communication between the LMBV and a large number of engineering service providers from different disciplines of engineering and geosciences, authorities as well as executing companies with specialisation in the fields of subsoil improvement, special civil engineering, earthworks and civil engineering, well construction, etc. The project was carried out in close cooperation with the LMBV.

For the cause research of the landslide event, for the rehabilitation planning of the slopes and for the mining law approval procedure, a complex groundwater flow model was set up by IBGW GmbH. The programme system PCGEOFIM, which was especially developed for the montane hydrological requirements, was used, in which the progressing opencast mine rehabilitation works, the flooded opencast mine lakes as well as the changing water balance components due to the recultivation measures are taken into account. For a qualified description and prognosis of the groundwater recharge caused by mining, the entire water balance, including the surface runoff, is reproduced via a coupling with a soil water balance model.

With expertise, innovation and know-how from the region and Germany, we are shaping a future worth living together.
