For more than 20 years GMuG is engaged in studies of rock salt and clay stone (please see publication list for further information). Another emphasis are measurements in deep mines (e. g. hard rock, crystalline).
GMuG performs both active measurements such as ultrasonic transmission or reflection measurements as well as passive monitoring of microseismicity and acoustic emission.
Measuring systems of GMuG are operated among others in the following facilities:
- Ezulwini Gold Mine (ZA)
- Grimsel Test Site (CH)
- Mponeng Gold Mine (ZA)
- Repository for radioactive waste Morsleben (D)
- Research Repository Asse (D)
- Rock laboratory Mont Terri (CH)
- Salt Mine Bernburg (D)
- Salt Mine Merkers (D)
- Underground Laboratory Mol (B)
In addition to measurements underground GMuG performs AE studies and ultrasonic transmission on laboratory scale e. g. in a triaxial press.
Measuring devices, sensors and software are developed and manufactured by GMuG. All measuring systems in mines or in laboratories work fully automatically. On-line (realtime) analysis is possible.
