1004 米！全球首台千米级竖井硬岩掘进机鞍钢贯通

On June 1, the Steel Backbone, independently developed by CRCHI, completed 1,004 meters of excavation at Ansteel’s West Anshan Iron Mine, marking a milestone: the world’s first kilometer-level deep vertical shaft built with a full-face vertical shaft boring machine (VSM) has achieved breakthrough completion.

6月1日，铁建重工自主研制的“钢铁脊梁号”在鞍钢西鞍山铁矿完成1004米掘进，世界首条全断面竖井掘进机施工千米深竖井贯通。

The equipment has conquered multiple world-class technical bottlenecks, delivered original innovations in deep underground engineering machinery, and made it to the list of the Top 10 Core National Equipment of Central SOEs 2025.

该装备攻克世界级难题，实现深地工程装备原始创新，入选2025年度央企十大国之重器。
