China News Service, Baise, May 8 (Chen Qiuxia) On May 8, the reporter learned from the Karst Geology Institute of China Geological Survey Bureau of the Ministry of Natural Resources that the institute organized a scientific expedition team to confirm the discovery of 1 in Leye County, Baise City, Guangxi. A standard sinkhole.
So far, the number of tiankengs in Leye County, the "tiankeng capital of the world", has increased to 30.
Zhang Yuanhai, a senior engineer at the Institute of Karst Geology, China Geological Survey, introduced that after UAV photogrammetry, the mouth of the tiankeng is flat and oval, 306 meters long from east to west, 150 meters wide from north to south, 192 meters deep, and the average depth is about 139 meters. meters, with a volume of more than 5 million cubic meters, reaching the standard of Tiankeng.
