Meriwa Report No. M236 (MERIWA Report No.186)
This three year project was designed to:
- Improve and optimise techniques for slope monitoring data collection;
- Develop rigorous mathematical models and software packages for monitoring data processing, analysis and visualisation;
- Develop integrated systems for on-line data logging, analysis and presentation, and for interfacing with other packages and alarm systems;
- Better understand the deformation mechanism of pit walls.
Research that was carried out in the project is reported under the following headings:
- Review of current slope monitoring techniques and practices;
- Development of an automatic slope monitoring system;
- Study of robotic survey systems for pit slope monitoring;
- Development of techniques and software for survey data processing and analysis;
- Analysis and modelling of deformation monitoring data; and
- Study of GPS technology for pit slope.
The report has contributed to a better understanding of the problems associated with slope stability monitoring, and has produced outputs beneficial to the Western Australian open pit mining industry in both short and long-term.
