The objective of this program was to develop a cost-effective microprocessor-based electronic image sensor for monitoring pit slope displacement to detect and/or predict impending slope failure in surface mines. A background study and data analysis yielded a performance specification for candidate video slope monitoring systems. A design concept was developed based on using a pair of solid-state video cameras located on precision pointing assemblies. The digital images from the cameras are compared and, using electronic triangulation, slope topology is calculated. The current and past locations of operator-selected features are compared to determine pit slope displacement. A proof-of-concept test was performed using a laboratory model of a pit slope. Based on the successful results of that test, it is recommended that an in-mine evaluation be performed using a full-scale prototype video slope monitoring system.
