Premature brittle failure of rock & cable bolts due to stress corrosion cracking can cause fatalities and serious damage, and has been reported in several mining operations across Australia and world-wide. The evidence suggests that microbial activity is a contributing factor. The project aims to implement experimental methodologies to determine the specific conditions responsible for bolt failure and develop novel prevention techniques applicable in underground mines. The benefits of this research will be improved understanding of the environment causing catastrophic failure of bolts and avoidance of potential hazards & economic loss in mining projects. This will lead to improved safety & increased productivity in mining operations.

由于应力腐蚀开裂导致的岩石和电缆螺栓的过早脆性破坏可能导致死亡和严重损害，并且在澳大利亚和世界各地的几个采矿作业中已有报道。有证据表明，微生物活动是一个促成因素。该项目旨在实施实验方法，以确定导致锚杆失效的具体条件，并开发适用于地下矿山的新型预防技术。这项研究的好处将是提高对导致锚杆灾难性失效的环境的理解，并避免采矿项目中的潜在危险和经济损失。这将提高采矿作业的安全性和生产率。
