Detecting Surface Changes from an Underground Explosion in Granite Using Unmanned Aerial System Photogrammetry

Abstract: Abstract-Efficient detection and high-fidelity quantification of surface changes resulting from underground activities are important national and global security efforts. In this investigation, a team performed field-based topographic characterization by gathering high-quality photographs at very low altitudes from an unmanned aerial system (UAS)-borne camera platform. The data collection occurred shortly before and after a controlled underground chemical explosion as part of the United States Department of En… Show more

“…There is subsidence of 0.0300 m near GZ and a maximum subsidence of 0.0630 m to the southwest of GZ. Ground deformation occurs over approximately 60% of the experimental pad with a horizontal linear extent of approximately 60 m. This InSAR result is smaller in magnitude but shows the same extent of deformation as optical photogrammetric measures of the SPE-5 explosion surface deformation [39]. The InSAR magnitude and extent results are comparable to results from airborne LIDAR height measures of the SPE-5 experimental pad before and after the SPE-5 explosion [2].…”

“…Several aspects of applied Earth sciences and engineering stand to advance tremendously with increased robustness in very small-scale change detection, including global security research, monitoring and potential early warning for high-consequence natural hazards like landslides and earthquakes, and time-varying stability analyses of critical infrastructure such as dams and tunnels. A critical application space for centimeterscale change detection is underground explosion monitoring [37,38]. Subtle surface changes from underground explosions create challenges in the interpretation and association of surface changes with explosion events, especially without high temporal cadence on topographic data collection.…”

“…However, the constraints on these older interpretations use measurements of offsets on fractures and level lines, which have a limited spatial extent and may miss subtle changes over the full area of interest. Recent topographic studies of underground conventional high-explosive experiments, using terrestrial light detection and ranging (LiDAR) and UAS-based SfM photogrammetric data, detected surface changes with a vertical magnitude of less than 15 cm in an underground conventional high-explosive experimental test bed in granitic rock [37]. Schultz-Fellenz et al ( [38], 2020) discussed the difference between the surface changes resulting from underground conventional highexplosive experiments and those from legacy underground nuclear explosions (conducted prior to the 1992 nuclear testing moratorium), and hypothesized that geologic setting may play a more significant role in governing the spatial extent and topographic expression of surface changes resulting from underground explosions.…”

“…Therefore, when developing minerals, one cannot do without competent mine surveying. The mine surveying service provides all the work on the extraction of minerals, develops measures for the rational use of subsoil and land, and performs work on the observation of the rocks movement and the ground's surface [13][14][15][16].…”
