TRE ALTAMIRA is delighted to be a part of the Mine Closure 2019 Conference in Perth (Western Australia), September 3-5!
A key feature of the conference series is the diversity of disciplines and expertise that come together to focus on the pressing issues facing the mine closure community globally.
As mines enter the closure phase, InSAR monitoring plans can be drawn up to meet the requirements of individual sites. While active mines require frequent updates with high-resolution imagery to allow geotechnical engineers to react quickly to changes in ground deformation; once a mine ceases operations, a decreased frequency and lower resolution imagery are often sufficient for the monitoring program.
While both active and closed mine monitoring solutions are preventative, closed mines are typically monitored with a lower data processing frequency (e.g. annual). Often the satellite imagery used is the publicly available Sentinel-1 data providing a more cost-effective solution while maintaining a high-temporal revisit frequency (12 days, or even 6 days in certain regions). The lower measurement point density still allows the characterization of deformation trends. However, in particular cases, it may be advantageous to monitor with high-resolution imagery during closure monitoring to identify localized deformation.
We invite you to join us at our booth #25 to learn more about monitoring closed mines using InSAR.
