ABSTRACT
This chapter describes common methods of monitoring movement of rock slopes, and interpretation of the results. It considers that monitoring programs are most appropriate for actively mined slopes such as open pit mines and quarries which have a limited operational life and where a carefully managed, on-going survey operation can be set up. Because of the unpredictability of slope behavior, movement monitoring programs can be of value in managing slope hazards, and they provide information that is useful for the design of remedial work. The chapter also describes common procedures for making surface measurements of slope movement. Surface measurements can only be used where the surface movement accurately represents the overall movement of the slope. Slope movement is most common in open pit mines, and many mines continue to operate safely for years with moving slopes that are carefully monitored to warn of deteriorating stability conditions.
