Freeport Mine in Indonesia is conducting feasibility studies for the mining of new underground mines in the Ertsberg district. Freeport needs to understand the state of stress that is likely to be encountered. The expected result of this program is to estimate and determine the magnitude and orientation of principal stresses for several locations.
The in situ testing program will comprise three phases where a minimum of five locations are to be tested. Stresses will be determined using CSIRO Hollow Inclusion Cells. ES&S is supplying all equipment and services for this major project.
