Abstract

As part of the SIT4ME research project, a hybrid method consisting of in-mine reflection seismic (Orlowsky et al. 2018), tunnel VSP (Br├╝ckl et al. 2001) and 3D borehole radar investigations (Orlowsky et al. 2016) is introduced. In this scope, both, active and continuous seismic measurements as well as 3D borehole radar measurements in the Asse II mine (Germany) were performed. The Asse II mine is a former salt mine used as a deep geological repository for radioactive waste, operated by the federal company for radioactive waste disposal (BGE). However, due to water penetration from the geological overburden and endangered stability of the mine workings, the German government ordered the retrieval of all waste material stored in the Asse II mine. For the retrieval, the operator plans to sink a shaft in direct proximity to the former emplacement chambers beyond the limits of the local salt dome. Consequential, the objectives of this study comprise the localization of the salt dome limits, the verification of known geological structures and the discovery of unknown stratigraphical and structural geological conditions.

Tim Hupe, BSc and MSc Geoscience at University of Bonn & Bochum (Germany), Now writing PhD thesis in Geophysics as part of SIT4ME about Passive Seismic Interferometry in Underground Mineral exploration: this includes the comparison of common in-mine exploration techniques with Passive Seismic Interferometry. Working experience during my studies at RWE, RAG and Uniper. At DMT: main task is processing and evaluation of geophysical measurements such as seismic, geoelectric, GPR; carrying out and plan international geophysical measurements.
