The field measurement (in-situ measurements) division at the IfG is responsible for the preparation and planning as well as the mining support and implementation of various geotechnical measurement methods in order to determine the characteristic rock mechanical behavior of underground support systems. The in-situ measurement data is incorporated into rock modeling and used to validate and calibrate numerical models.
In addition, our employees extract sample material and transport it to our rock mechanics laboratory for further mechanical and hydraulic testing. If necessary, we carry out all the necessary mining extraction work ourselves, such as solid drilling or core drilling with different calibers.
Our measurement engineers maintain direct contact with the mine operation, which enables fast and practical communication with our clients. This ensures that our modeling processes and results are realistically aligned with the actual conditions underground.
