Rock mechanics - measuring and monitoring

Rock stress measurements provide real-time data

Hydraulic fracturing is a coarse 2D stress measurement method that allows two principal stresses to be measured. Measurements can be taken from the ground or from below ground. The current equipment can be used in 100 m deep holes, but the depth scale can be increased if the project so requires. Measurement works in 46mm - 60mm holes.

GRM offers monitoring of rock stress changes with adhesive HID cells.

Monitoring with multiple sensors

A single automatic measuring instrument such as an extensometer or any other device measuring pressure, stress, collapse, displacement, pouring or temperature.

  • Multiple sensors connected to a larger logging system

  • Automatic alarms

  • Real-time data

  • Manual measurements such as tunnel convergence measurement

  • Automatic convergence measurement with the so-called Basset system

  • Rock mechanics Kalliomekaniikka

    All measuring devices can be made to produce real-time data and systems can be set to alarm limits.

    Measurements can be taken at ground level, underground and in boreholes.
