Restricted by the site geological condition, the most complicated part of the rescue mission is how to enter and exit the caves without risking the lives of any personnel. Through the geophysical exploration by GD-20 system, the suspected cave is over 500m below ground surface. However, by borehole logging analysis, the region of the suspected cave is shale layer instead of limestone layer. Exact cave location is therefore rapidly delineated from the hill peak direction through the data fusion from multiple exploration data. Food and water are initially transferred into caves to ensure the survival of the trapped members, while excavation works are performed gradually after inspecting geological conditions closely to pinpoint the cavity location.
The inverted resistivity profiles performed at the trapped area are shown as below:
After rescue mission of around four long days, the international rescue team achieved great success and rescued all 12 boys and their coach from the flooded cave.
In this rescue mission, GD-20 performed accurate and rapid survey through its multi-channel acquisition capability, rapid measurement, robust site adaptiveness and other powerful features. Survey conducted on the cave region of the trapped soccer team revealed the site geological condition, providing clear rescue direction and revealing potential risks at the same time. This powerful characteristic matches the concept held by Geomative Inc. for a long time, which is “ To be fully committed to environmental investigation, monitoring, remediation and protection and maintain the safety and sustainability of human’s living environment, with innovative technique, cutting edge products and the utmost professional attitude”. Geomative Inc, will strive to innovate in a pragmatic fashion, contributing our effort to the health and safety of our living environment.
