Situation

Rockfall hazard from the natural slopes above the mill area within the Grasberg mine had to be mitigated. After several incidents with boulders hitting buildings and infrastructure a fast and reliable solution had to be found.

Description

The RXE-8000 rockfall barrier was installed across a very active gully on the east side of the mill area. Several rockfall incidents with boulders up to 2 meters in diameter had affected the mill infrastructure before. To ensure safe operation of the mill area below the gully, the barrier was installed approximately 140 meters above office buildings and ore processing facilities.
