In recent years, there has been a trend towards testing and using radar-based monitoring
systems. The mines that use radar systems allow for continuation of mining in
areas that experience higher movement rates than would tolerated if just prisms were
used. Thus, radar monitoring has opened up new opportunities for pit wall management.
However, the large volume of data generated by these systems can create problems
with data processing and analysis and further experience is still needed to
optimise and define appropriate movement thresholds for different operational
responses.
