Expertise

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)
• Tau Tona Gold Mine (ZA)
• Underground Laboratory Äspö (S)
• Underground Laboratory Bedretto (CH)
• Untertagelabor Mol (B)
• Underground Laboratory Reiche Zeche Freiberg (D)
• Underground Laboratory Tournemire (F)

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.
