[Commentary] "Unmanned driving" technology is not new to everyone, but to apply it to a 13-meter-long, nearly 7-meter-high, 172-ton large mine card, but it faces many challenges. Recently, the reporter came to the Baiyun Ebo Iron Mine, which has the largest rare earth reserves in the world, where he saw an unmanned mining vehicle that was accurate to the centimeter level and has been in safe operation for more than 450 days, and explored the ongoing "smart mine" project here. exactly.
[Explanation] It is understood that there are currently 4 MT3600 mining dump trucks that have been unmanned. On these big guys with a weight of 139 tons, they are equipped with millimeter-wave radar, lidar, high-precision integrated navigation modules, The vehicle-mounted communication module and various sensors can be seen on the monitoring screen of the unmanned centralized control center of the road transportation operation department of Baiyun Ebo Iron Mine, and it can be seen that the unmanned mine car is being automatically loaded and planned according to the plan in the winding mine Transport ore mission.
[Same period] Xiao Liang, the person in charge of the unmanned driving project of Baiyun Ebo Iron Mine
In the industry of mines, we have (stuff) staff shortages, safety accidents (and other problems), including our (in) transportation process, (all aspects) high costs, so it also prompts us to drive this industry unmanned. Urgently to solve this demand for the pain points of the mining area. Unmanned driving is more efficient and safer, and the overall transportation cost (can be) reduced by about 10%. Therefore, with the development of communication and vehicle technology, we have new (breakthrough), for example, the intelligent scheduling platform we have seen, can dispatch unmanned vehicles.
[Commentary] Xiao Liang introduced to reporters that the current unmanned driving project has overcome the technical problems of perception fusion, motion prediction and planning, precise docking, automatic loading and unloading, and autonomous obstacle avoidance. The 4 unmanned mine trucks have achieved high-precision positioning, environment awareness, path planning, intelligent scheduling, and fault alarming through intelligent terminal equipment and monitoring and dispatching platforms. And it realizes the automatic operation of the marshalling with the electric shovel and the unloading point, which belong to the leading level in the industry.
[Commentary] The reporter learned that the increasingly perfect unmanned driving system is just one of the smart mining technology innovation projects being promoted by Baosteel Group Corporation. Based on 5G technology, intelligent safety monitoring and other projects will also be gradually applied to other production in the mining area. Link. A team composed of Baosteel Group, network operators, universities and technology companies is carrying out intelligent exploration and practice of various production links in Baiyun Ebo Iron Mine.
[Same period] Huo Guang, Deputy Director of Baiyun Ebo Iron Mine Equipment Department of Baosteel Group Corporation
We are now allowing mechanization to replace manual operations, including (among others) the unmanned driving that we are doing now. Using this model to replace people in the front line (work), we can release the most difficult workers in these front lines from these difficult positions, and can reflect our humanistic care. Through our present series of current intelligent methods, we have greatly reduced energy consumption and greatly improved environmental protection, and overall our production costs have also been greatly reduced.
[Commentary] Huo Guang told reporters that the rare earth reserves of Baiyun Ebo iron ore accounted for more than 41% of the world’s total proven reserves, and also produced 175 mineral resources such as iron, niobium, manganese, phosphorus, and fluorite. It is said to be an important resource base in China. The ongoing exploration and construction of smart mines here will undoubtedly provide an environmentally friendly and efficient sample for more than 500 open-pit mines in China.
[Same period] Huo Guang, Deputy Director of Baiyun Ebo Iron Mine Equipment Department of Baosteel Group Corporation
It is hoped that a model of this kind of smart mine that we are exploring now can provide a new (thinking) and model reference for major mines in the country, especially open-pit mines.
