Mining vehicle reaches record sea-trial depth

China’s deep-sea heavy-duty mining vehicle has completed a sea trial at a depth exceeding 4,000 meters, marking a significant breakthrough in the country’s deep-sea mineral resource development technology.

The trial was conducted by “Pioneer II,” an engineering prototype developed by Shanghai Jiao Tong University, the Shanghai government said yesterday.

“Pioneer II” completed five diving and seabed mining operations, including a record-breaking dive to 4,102.8 meters, marking the first time a Chinese deep-sea heavy-duty mining vehicle conducted trial operations at depths above 4,000 meters.

The mining vehicle has pioneered several innovations in the country, including high-mobility deep-sea navigation over complex seabed terrains and composite drilling and mining of multiple types of deep-sea minerals.

Yang Jianmin, chair professor at Shanghai Jiao Tong University and chief scientist of “Pioneer II,” said that during the sea trial, the mining vehicle completed one dive per day for five consecutive days from June 22 to 26 in the western Pacific Ocean, successfully obtaining over 200 kilograms of various deep-sea mineral samples.

Several prominent experts, including Lin Zhongqin and Li Jiabiao, both academicians of the Chinese Academy of Engineering, hailed the success of the sea trial as another solid step forward for China’s deep-sea exploration.
