And yet it moves!

This quotation from Galileo Galilei applies to the Earth itself as well: to the many small and medium movements within a mine layout, which mark the additional geomechanic dynamic of mined horizons. Recording, localising, determination of hypocentre and magnitude, and finally finding the correct conclusion of the above is the task of seismic monitoring by the geophysics department. Development of hard- and software, layout and engineering, construction and operation as ordered by the client, including daily analysis and alerting, and vibration measurements: this is our task, mining companies, cavern-operators, geothermal power plants, old mining and similar are our clients for stationary or temporary seismic monitoring systems.

Uncover the invisible...

… is the ambition of our geophysical exploration experts. Different geophysical survey methods, state of the art technology, decades of know-how, predominately in potash- and salt-mining: based on these ingredients we extract data for the client, about his deposit, underground, dykes, open cast mining disposal area and so forth. This data will be a solid basis for the client's decisions and actions. Whether above or below ground, in drill holes or on salt deposits, we will uncover what was invisible before – by the exploration of e.g. near-surface cavities or stratigraphy, applying seismic, geoelectrical, or ground penetrating radar techniques.
