Abstract: 　Mineral resources serve as the cornerstone of national economic security and industrial development,while deep mining constitutes a strategic approach to address the high external dependence on critical minerals and insufficient sup ply chain resilience.In the face of extreme geological conditions and complex construction environments in deep metal mining operations,the structural defects of the traditional drill-blast method in terms of efficiency,safety and cost have become increas ingly prominent.As a preferred solution for the intelligent transformation of mine roadways,the full-face hard rock Tunnel Bor ing Machine (TBM) offers comprehensive advantages including high safety,efficiency and tunneling quality.This paper sys tematically analyzes the engineering characteristics and mining demands of metal mines,and constructs a dedicated TBM tech nological innovation system adapted to metal mines around five dimensions:advanced geological detection and real-time percep tion,equipment structural integration and flexibility,enhanced stratum adaptability,efficient roadway construction technology, and intelligent remote control.The system has successfully broken through key technical bottlenecks such as ultra-small turning radius,steep slope and long-distance hard rock tunneling,and these breakthroughs have been verified in a number of typical projects.Finally,this paper prospects the future development directions of mining TBM,such as transparent geology adaptation and equipment diversification.The research results not only expand the application theory and technical system of mining TBM,providing a complete set of solutions for the efficient,safe,green and intelligent mining of deep metal mines,but also pos sess significant theoretical value and engineering significance for improving the self-sufficiency of critical mineral resources and promoting the intelligent transformation of mines.
