Method, system and computer program product for real-time monitoring of stress changes in an excavation

A method for real-time monitoring of stress changes in an excavation (100), suchas in a mine or a tunnel comprises determining (410) strain data of the excava-tion by at least three strain measurement devices (15, 25; 15A-15C), whereinthe strain measurement devices (15, 25; 15A-15C) are arranged sur...

Zusammenfassung:A method for real-time monitoring of stress changes in an excavation (100), suchas in a mine or a tunnel comprises determining (410) strain data of the excava-tion by at least three strain measurement devices (15, 25; 15A-15C), whereinthe strain measurement devices (15, 25; 15A-15C) are arranged surroundingthe excavation (100) to determine the strain data along different directions withrespect to each other, receiving (420) the determined strain data on a pro-cessing unit (50) arranged in connection with the strain measurement devices(15, 25; 15A-15C), and back-calculating (430), by the processing unit (50), astress change based on the received strain data.
