Geotest Projects TERNA Magnesites, Bobakas Geotechnical, Greece

Project Information

TERNA Magnesites operate in Evvia, central Greece and is the main producer of magnesite in Greece from a number of underground and open pit operations. Concerning open pit slope stability and danger zone identification, we provided a complete geotechnical assessment prior to mining in Bobakas open pit.

Value :1.0 M€
Drilled :1,000 meters

Project Description

The project included data collection though drilling, geotechnical logging and field mapping to support Bobakas open pit geotechnical assessment. One (1) surface drilling rig and our experienced geological took over data collection and analysis.

Project Challenge

Slope stability and open pit requires special attention to avoid failure during mining.

Oriented drilling and core analysis
Weak zone identification and measurements proposal

RESULTS

A rockmass classification scheme was shaped. Pit design was confirmed for its slope stability and protective measurements were suggested to avoid failure in the identified weak zones.
