South Korean robot successful deep-sea mining test Seoul, August 4 (Xueyan) the South Korean Ministry of marine and Fisheries and the South Korean Academy of marine science and technology said on August 1 that South Korea successfully used robots to conduct mining tests on the deep seabed

the mining test was conducted 130 kilometers southeast of Pohang, Gyeongsang Hokkaido, South Korea. The robot used in the test dug the seabed manganese nodule model at a depth of 1370 meters. The mining robot is independently developed by South Korea and is named Minero. The robot is 6 meters long, 5 meters wide, 4 meters high and weighs 28 tons. It is equipped with mobile crawler, buoyancy system, mining and storage system. It can search for manganese nodules on the seabed without the instruction of the mother ship

the ultimate goal of the Korean government is to mine manganese nodules on the seabed in the Pacific Ocean, 2000 kilometers southeast of Hawaii, with a water depth of 5000 meters. It is estimated that there are 560million tons of manganese nodules in this sea area alone. The Korean government believes that if the mining is successful, there will be an import substitution effect of 2trillion won per year. Wen Hainan, head of the Marine Policy Office of the Ministry of marine and Fisheries of the Republic of Korea, said that according to the current trend, the commercialization of relevant technologies can be completed in 2023

in 1994, the Korean government applied for this sea area as an exploration mining area in the United Nations, and in 2002, it obtained an exclusive exploration right of 75000 square kilometers in the International Seabed Authority (ISA). As the exclusive exploration right ends in 2015, the Korean government plans to ensure the mining technology before that and apply to isa for extension of the exploration right. In this successful robotic mining, the machining allowance can be appropriately reduced according to the agreement of both parties. After the test when the stress continues to increase to point C, the South Korean side will mainly study how to pump the excavated manganese nodules to the mother ship, because this technology can have real economic value only if the important means of mining and transportation are successful at the same time
