Metallurgical Influences on Stress Corrosion Cracking (SCC) of Rock Bolts (2004–2006)

Abstract:
This project seeks to understand the metallurgy of stress corrosion cracking (SCC) of rock bolts. Rock bolts are the most effective means of roof support in underground mines and, as a consequence, rock bolts are widely used in the mining industry worldwide. Failure of rock bolts by SCC has significant safety and economic implications. The consequent rock falls have the potential to kill or main any person caught underneath. If a stoppage is caused of the long wall operation in a typical Australian colliery, the typical value of the lost production is of the order of a million dollars a day.
