BfS wants a seismic exploration of the Asse
Measurements shall produce a more detailed knowledge of the mine - Public information event in Remlingen

location Remlingen
Next year, the Federal Office for Radiation Protection (BfS) intends to conduct seismic measurements in the area of the Asse II mine. With the help of 3-D seismic measurements a more detailed knowledge of the mine shall be gained. The measurements will take around three months; results should be available in 2013 at the latest. Preliminary work is currently carried out by Gesellschaft für Geowissenschaftliche Dienste from Leipzig (GGD). In a public information meeting held on 3 June in the Remlingen village community centre, citizens had the opportunity to get extensive information about the project.
Geophones record acoustic waves
The head of the BfS’ field of expertise “Asse decommissioning”, Dirk Laske, and Tobias Karp, GGD project manager, explained the process to an audience of more than 70 people. So-called vibration vehicles generate acoustic waves, which are then recorded with a so-called geophone, which works similar to a microphone.
Using geophysical analysis and modelling will provide the scientists with a three-dimensional picture of the geological structure, which is much more detailed than the two-dimensional measurements, which the former operator carried out in the Asse region. The idea is that with the help of 3-D imagining, the path of saline solutions into the Asse can be determined more accurately.
The seismic data will be collected in an area measuring 18 square kilometres around Wittmar, Mönchevahlberg, Groß Vahlberg, Remlingen and Klein Biewende.
Measuring company must enter premises
In order to collect the data, the measuring company must access premises in the investigated area. Experts must lay measuring cables, install geophones and set up transmitting points. Prior to this, licence/access agreements are signed with the owners. Surveys are carried out before and after the premises were accessed. Generally no damage occurs during the procedure. Should in isolated cases any damages occur, they will be reimbursed.
