first! my country's deep-sea heavy-duty mining vehicle test water depth exceeds 4,000 meters

China's deep-sea heavy-duty mining vehicles have made a major breakthrough, with the sea test water depth exceeding 4,000 meters for the first time. This achievement marks that my country's deep-sea mining equipment development technology has reached a new level. Deep-sea heavy-duty mining vehicles are important equipment for the development of deep-sea mineral resources, and their operating depth is directly related to mining efficiency and resource utilization. The success of my country's sea trial this time fully demonstrates my country's strong research and development capabilities in the field of deep-sea equipment. The following will introduce in detail the specific situation of my country's deep-sea heavy-duty operation mining vehicle breaking through 4,000 meters of water depth in sea trials, and the impact of this achievement on my country's deep-sea mining industry.

News on July 9, According to media reports, my country has made major breakthroughs in key technology research and equipment development for the development of deep-sea mineral resources.

The engineering prototype of the deep-sea heavy-duty mining vehicle "Kaituo No. 2" independently developed by Shanghai Jiao Tong University has successfully completed sea trials.

"Kaituo 2" has completed 5 consecutive bottom mining operations and recovered deep-sea polymetallic crusts and nodules. The water depth of the deep-sea heavy-duty operation mining vehicle has exceeded 4000 meters for the first time, with the deepest reaching 4102.8 meters, It is the first in China to pioneer many technologies in the field of deep sea mining such as high maneuverability in complex seabed terrain and deep sea multi-mineral composite drilling.

It is reported that "Kai Kai No. 2" is 6.0 meters long, 3.0 meters wide and 2.5 meters high. It weighs about 14.0 tons in the air and is designed to operate in a water depth of 6,000 meters.

It is the first in China to break through the complex seabed terrain adaptive four-track travel, multi-metal sulfide integrated cutting and drilling, deep sea environmental acoustic/optical comprehensive sensing, seabed mining operation intelligent control, deep sea non-metallic umbilical cable heavy load deployment It also provides key technologies such as recycling, and is equipped with comprehensive environmental monitoring equipment such as deep-sea plumes and underwater noise.
