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.

本项目旨在了解岩石锚杆应力腐蚀开裂（SCC）的冶金学。岩石锚杆是地下矿山中最有效的顶板支撑手段，因此，岩石锚杆在世界范围内广泛用于采矿业。应力腐蚀开裂导致的锚杆失效具有重要的安全和经济意义。随之而来的罗克瀑布有可能杀死或主要的任何人被困在下面。如果在一个典型的澳大利亚煤矿中，停工是由长壁作业引起的，则损失的产量的典型价值为每天100万美元。
