Racing Against Time: Sichuan Coalfield Geophysical Exploration Team Rushes to Jiangyou for Emergency Rescue
Around 10 a.m. on May 25, after receiving orders from the leadership of the Sichuan Provincial Coalfield Geology Bureau to provide emergency support for the tunnel collapse at the Wudu Water Diversion Project, Sichuan Zhongcheng Coalfield Geophysical Exploration Engineering Institute Co., Ltd. promptly established a geophysical exploration technical team. After contacting the Joint Command Center for Emergency Rescue, the team immediately set off and arrived swiftly at the site by noon that same day. Based on the preliminary information they had gathered, the geophysical exploration team conducted a targeted on-site survey of the collapsed section of the tunnel. Due to the narrow cross-section of the tunnel at the site, severe blockages caused by the collapse, and the highly complex conditions in the buried area, on-site rescue efforts were severely hampered. The geophysical exploration team optimized its approach based on the actual situation and designed three geophysical profiles: one along the tunnel’s axis and two intersecting obliquely with the tunnel’s axis. At 7 p.m., the geophysical exploration team began field operations according to the designed plan. After working through the night, they successfully completed the field data collection by 3 a.m. on May 26. Subsequently, the geophysical exploration team processed and inverted the collected data in conjunction with geological information provided by the Joint Command Center for Emergency Rescue, quickly pinpointing the location of the collapsed area. Their findings confirmed the rescue expert group’s initial prediction of the collapse zone, laying a solid foundation for the next phase of scientific rescue operations.
Based on the results provided by the geophysical exploration team, the Joint Command for Emergency Rescue formulated a rescue plan featuring “small progress increments, full-face excavation, robust support, and steady advancement.” After 176 hours of relentless efforts by emergency rescue teams from various sectors, at around 8 p.m. on the 29th, all three trapped individuals were successfully rescued, creating yet another miracle in Sichuan’s rescue history!
For decades, the geophysical exploration team from Sichuan Coalfield has been deeply engaged in fields such as tunnel exploration, engineering geophysics, and shale gas exploration. With solid technical expertise and extensive experience, they raced against time during this emergency rescue operation, demonstrating courage and taking the lead. Their outstanding performance provided crucial technical support for the successful rescue effort. Leaders from Mianyang City and Jiangyou City, as well as the Joint Command and Expert Panel for Emergency Rescue, have highly praised their exceptional contributions.
