Numerous multiple rod extensometers with up to 60 m individual rod lengths were supplied and installed for the geotechnical rock mass monitoring of individual flushing plants, which have an extension of up to 160 m x 120 m and a height of up to 125 m. The installation was carried out in the ridge and the roof of the mine. The installation was carried out in the ridge and floor of existing galleries.
