A corrosion study was conducted for a deep level mine to determine the corrosion rates of different steel types and coatings for split set rockbolts subjected to various underground environmental conditions. Testing was conducted underground in ramps and intake and exhaust airways. In addition, simulated underground corrosion testing was carried out in a laboratory. The study found that the different underground environments had no significant impact on corrosion rates. Duplex coating was found to be the most corrosion resistant, followed by zinc-based coatings. Uncoated steels performed the worst.
