Four missing personnel from the China Geological Survey in Ailao Mountain, Yunnan have been found and all have been killed and their identities disclosed
According to the video data of the rescue scene, the names of the four missing investigators were Yang Min, Zhang Jinbang, Zhang Yu, and Liu Yu (audio). Wang Hongdong, director of the Zhenyuan Management and Protection Bureau of Yunnan Ailaoshan National Nature Reserve, said that these missing persons, the oldest 32 years old and the youngest 25 years old, had all served as soldiers.
On November 13, four staff members of the Kunming Natural Resources Comprehensive Survey Center of China Geological Survey lost contact during field operations in Ailao Mountain, Yunnan. At 19:28 on November 15, the People’s Government of Zhenyuan County received a related report of loss of contact.
The four personnel lost contact after entering Ailao Mountain from Zhangpen Village, Zhedong Township, Zhenyuan County. After receiving the report, Zhenyuan County immediately established a “11.15” rescue headquarters for missing persons. As the lost connection is located in the Ailao Mountain National Nature Reserve, with steep mountains, dense trees, and ravines, with an average altitude of over 2500 meters, the geographical environment is very complex. In addition, the local area has been rainy and heavy for several days, which brought great search and rescue work. difficulty.
As of 12:00 on November 21st, more than 1,400 professional search and rescue personnel, more than 130 vehicles, 18 satellite phones, 8 drones, 5 helicopters, 3 police dogs and related materials and technical equipment have been put into this rescue. The operation, the cumulative search and rescue area is about 60 square kilometers. According to the command plan, the search and rescue work is a carpet-style precise investigation, and the later focus is on the deep trenches, cliffs, deep pools and other key areas around the shack where the missing persons lived.
As of the afternoon of the 21st, all search and rescue teams were still engaged in search and rescue efforts in Ailao Mountain. On the evening of the 21st, the staff of the search and rescue front-line headquarters told the Red Star News reporter that there was “significant progress” in the search and rescue work. The Red Star News reporter saw that stretchers and ambulances rushed to the scene, and the headquarters imposed stricter traffic control on Zhangpen Village.
Four geological survey personnel who lost contact with the mountain came to the mountain this time originally to carry out a two-day forest resource survey, using RTK (real-time differential positioning) equipment to calculate and count the forest sample plots. In an interview with the Beijing News, a rescuer introduced that RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. The 4 people who lost contact each have an RTK device. According to the plan, they should turn on the RTK device on November 14. As long as the device button is pressed, rescuers can find the location of the four people based on the data returned by the satellite system. However, from the 14th to the 21st at 11 o’clock, the four people who lost contact had never opened the RTK equipment, so rescuers could not locate them.
