The management of risks associated with slope instability is an essential process in the safe and economic operation of open cut mines. The slope stability radar' (SSR) has been developed to better manage those risks. The SSR can remotely scan a rock slope to continuously measure any movement of the face. The system can detect and alert users of wall movements with submillimetre precision. The high level of movement precision and broad area coverage of the rock face can allow for a better understanding of the geomechanics of slope deformation, including magnitude of potential failures and additional warning time of impending instability. Additionally, radar waves adequately penetrate through rain, dust and smoke to give reliable measurements, 24 hours a day._x000D_
SSR systems have been deployed in many mines in Australia, Indonesia, Africa, Chile and the United States. Greater than 100 rock falls and waste dump failures (from several tonnes to millions of tonnes) have been monitored, and on every occasion precursor warning' movements were recorded by the SSR. This technology enables a radical change in the management of risks in open cut mining. This paper presents recent case studies of how the SSR technology has provided safety and productivity benefits to large open cut metalliferous mines._x000D_
