Corrosion of rock reinforcement in underground excavations

Summary

By undertaking field investigations at eight of the sponsors’ minesites, this project set out to determine the main corrosion mechanisms that affect rock reinforcement elements used underground.

Objectives included both in situ testing of reinforcement elements and simulated corrosion experiments in chambers at the Western Australian School of Mines.

The final report details results of these tests and offers recommendations in practise.
