Integrated monitoring systems for open pit wall deformation

Summary

The following methods were developed:

• the design and optimisation of slope monitoring networks to determine optimum locations of survey instruments and prisms, through computer simulations;
• deformation mechanism of slopes, based on the observed deformation data from monitoring surveys, using least squares linear regression analysis technique;
• integrating monitored deformation data in numerical modelling of slope deformations;
• a comprehensive evaluation of the performance and suitability of a robotic survey system for pit slope monitoring which showed a survey accuracy approaching that of manual survey operations; and
• an automatic slope monitoring system for automatic acquisition, transmission and management of deformation measurement data.
