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.

由于压力腐蚀破裂而导致的岩石和电缆螺栓的过早易碎破坏会导致死亡和严重破坏，并且在澳大利亚和全球的多项采矿作业中据报道。证据表明微生物活性是一个促成因素。该项目旨在实施实验方法，以确定导致螺栓故障的特定条件，并开发适用于地下矿山的新型预防技术。这项研究的好处将改善对环境的理解，从而导致螺栓的灾难性故障，并避免采矿项目中潜在的危害和经济损失。这将导致提高安全性和提高采矿业务的生产率。
