GFZ-Underground-Lab in the education and research mine "Reiche Zeche" of the Technical University Bergakademie Freiberg

 

Description
 

Reiche ZecheThe GFZ-Underground-Lab is situated 150 m below surface on the first floor in the education and research mine "Reiche Zeche" of the Technical University of Freiberg. Surrounded by three galleries the measuring site comprises a block of homogeneous high grade gneiss of almost 50 m width and 100 m length ensuring constant environmental conditions. Along the galleries over thirty 3-component one and two meter long geophone anchors are installed with a distant of 4-9 m from each other. Two horizontal 8 ½" boreholes of 20 and 30 meters were drilled into the measuring site. In 2011 the GFZ-Underground-Lab has been extended by a chamber 10 m above the galleries. From up there a 70 m 8 ½" vertical borehole has been drilled through the gneiss block. All boreholes are open and completely cored.
The Underground Lab Is used to test newly developed seismic systems and there components e.g. receivers and sources for 3-dimensional high resolution seismic imaging and tomography surveying. 3D GFZ-Underground Lab
