• Description:
  Conventional ground-based instrumented displacement monitoring can be labor intensive and time consuming, particularly when monitoring a large or complex mine environment. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) provides a safe, economical monitoring option in providing coverage of large areas and critical interests of mine sites. In April 2023, researchers at the National Institute for Occupational Safety and Health (NIOSH) collaborated with SkyGeo Inc. and industry partners of the Highwall Safety project to back analyze recent slope failures in Nevada and identify whether there were early indicators of instability leading up to the events. This paper presents the results of each back analysis and outlines a path forward on continuation of this work throughout the duration of the NIOSH Highwall Safety project. This research coincides with the development of a comprehensive slope failure evaluation database as discussed by NIOSH at Slope Stability 2022 in Tucson, Arizona. [Description provided by NIOSH]
