Monitoring surface deformation over mining assets is highly important. Unanticipated movement of any rock mass can cause risk to workers and equipment, mining infrastructures, and disrupt mine scheduling with an increase in production cost.
Advanced InSAR techniques are capable of measuring and accurately characterizing ground deformation remotely due to their unique capacity to provide dense point clouds of deformation measurements coupled with a history of movement over time. Recently, remote monitoring of ground deformation has become a standard tool for the early detection of ground movement over mines sites world-wide.
While InSAR techniques have long been able to provide accurate deformation rates over a mine’s total surface assets, results were not presented at a frequency to meet operational planning and monitoring needs. Satellites observations were limited to 24, 35, or even 46 day time intervals. Now with 16, 11, 8, and even 4 day revisit times of the current modern satellites, the data collection cycle has vastly improved. The reporting time cycle has also improved with advanced InSAR techniques and tools that can process the increased data loads and provide critical deformation information to the Geotechnical Departments on operational planning time schedules.
