Recently, China's largest single underground iron ore project, Anshan Iron and Steel West Anshan Iron Mine, has once again become the focus of global attention after a solemn start in November. Why is it so compelling? It turned out that a journey of underground miracles was being set off here, led by the full-section hard rock tunnel boring machine "Cornerstone"!
Explore the top of Anshan
Located in Anshan City, Liaoning Province, the West Anshan Iron Ore Project is not only the largest underground iron mine in China, but also the first to use TBM (full-section hard rock tunnel boring machine) in China. Officially started in November 2022, the project has strong technical support behind it, marking a new era in the construction of underground iron mines in China.
Cornerstone: Underground
The "Cornerstone" has a total length of 188 meters and an excavation diameter of 703 meters, with a total weight of 1,200 tons, this behemoth will become an explorer in the underground of Anshan. Compared with the traditional drilling and blasting method, it not only has a qualitative leap in construction speed, but also is synonymous with environmental protection and high efficiency. It is reported that after being put into use, the comprehensive efficiency of construction will be increased by more than 3 times, injecting strong technical power into the underground project.
TBM: The best tool for underground construction
TBM is not an unfamiliar term, but it is the first time it has been used in iron ore mines. This full-section hard rock tunnel boring machine is not only an excavator, but also an underground construction treasure book that integrates tunneling, support, slag removal and other processes. The rapid tunnelling speed, environmental protection and pollution-free overall efficiency far exceed that of traditional methods, which means that construction in complex geological conditions will become more relaxed.
The pinnacle of technology in underground nuggets
The debut of "Cornerstone" has opened a precedent for the research and application of TBM key technologies and equipment at home and abroad. This initiative is not only the pride of Anshan, but also a technological leap forward in the field of underground construction in China. In the future, we may witness more technological miracles in the underground space, and the "Cornerstone" will become the pinnacle of technology in this underground nugget.
The tacit dance music of the laborers
In the construction of this underground city, the laborers are like tacit dancers, and the "Cornerstone" plays a symphony of underground construction together. Their hard work is the true cornerstone of this underground city. It deserves our constant attention and tribute!
Environmental Pioneer: The Green Choice for Underground Construction
The application of "Cornerstone" is not only unique in terms of efficiency, but also leading in terms of environmental protection. Compared with the traditional drilling and blasting method, it does not need to be blasted, which avoids the generation of surface vibration and noise, and protects the surrounding environment. In this era of focusing on green development, the application of TBM will become a green choice for underground construction.
A sequel to the miracle
The debut of the "Cornerstone" is like a sequel to an underground miracle, injecting technology and vitality into the construction of iron mines. And the sequel to this miracle will gradually unfold in the underground depths of Anshan, exploring the unknown and creating more possibilities.
Looking to the future: a new era of tunnelling technology
With the launch of the Cornerstone, we are looking forward to the future of underground construction. In this era of rapid development of science and technology, underground engineering will usher in more innovation and more application of technology, and the "Cornerstone" will become a huge opportunity for this new era of science and technology.
Conclusion: The wonder of the underground, the beauty of science and technology, from the depths of the underground of Anshan, a new era of underground construction journey kicked off!
