A comprehensive and robust performance monitoring system is an essential component of the slope management program in an open pit mining operation. Local conditions and experience should drive the planning and implementation of the monitoring program, and development of an early warning system. Knowledge of the capabilities and limitations of the instrumentation selected to ensure the monitoring system is and remains effective and reliable is emphasised. Another important consideration includes the appropriate skill sets of the geotechnical personnel who are responsible for maintenance of the monitoring system and for implementing standard procedures required to ensure operational safety. With the increasing volume of data generated by modern electronic slope monitoring equipment and with an increasing variety of sensors, there is a growing need to combine and integrate the data in efficient, effective, and innovative ways. It is important that geotechnical staff do not spend their time wading through continuously mounting data but instead focus on data interpretation, reliable results reporting, and addressing urgent actions as needed. A slope monitoring system must be capable of treating all data from different sensors in a collective unified way to facilitate rapid compilation, data cross-validation, analysis, and timely reporting of results. A mining operation must address the adequacy of its performance monitoring program through its risk management process. This paper describes the requirements of a slope monitoring system to achieve performance reliability and data quality assurance, and in this context includes an introduction to the large open pit project’s ‘Guidelines for Slope Performance Monitoring’, which is in development. This upcoming book provides a description of the process involved in establishing and operating a reliable slope monitoring system; describes the fundamentals of pit slope monitoring methods; application; data acquisition, management, analysis; and, utilisation and communication of monitoring results.
