As shallow metal mineral resources become increasingly depleted, advancing into the deep subsurface has become an inevitable strategic choice for safeguarding national resource security. However, the complex geomechanical environment characterized by "three highs and one disturbance" in deep mining poses severe challenges to conventional stoping methods in terms of safety, cost control, and operational efficiency. By reviewing typical engineering practices of deep mines at home and abroad and recent research achievements, the development status, key engineering technical difficulties, and main technological paths of deep metal mining were systematically summarized. The applicability and limitations of deep mining methods under different ore body occurrence conditions was analyzed, and it was pointed out that "large-scale mining, intelligent equipment, and continuous operation" constitute the core direction of deep mining technological transformation. For three typical types of ore body occurrence conditions, namely thick and stable ore bodies, fractured ore bodies, and thin veins in deep mining, technical systems were respectively proposed with high-stress coupled rock fragmentation and modular continuous stoping, environmental reconstruction and stress-relief mining, as well as precise blasting and waste-free efficient stoping as the core. Meanwhile, the application potential of non-explosive mechanized continuous mining technology in reducing disturbance and enhancing inherent safety was also analyzed. This study aims to provide a theoretical basis and technical pathways for the transformation of deep metal mining in China from traditional modes to intelligent and continuous technology systems, thereby contributing to the formation of new quality productive forces in metal mineral resource development.

随着浅部金属矿产资源日益枯竭，向深部进军已成为保障国家资源安全的必然战略选择。然而，深部“三高一扰动”的复杂地质力学环境，致使传统回采工艺在安全性、成本管控及作业效率等方面面临严峻挑战。通过梳理国内外典型深井矿山工程实践与近年科研成果，系统综述了金属矿深井开采的发展现状、关键工程技术难点及主要工艺技术路径，分析了不同赋存条件下深井采矿方法的适用性和局限性，指出“开采规模化、装备智能化、作业连续化”是深井开采技术变革的核心方向。针对深部厚大稳固矿体、破碎矿体及薄矿脉三类典型矿体赋存条件，分别提出以高应力耦合破岩与模块化连续回采、环境重构与卸压开采、精细化爆破与无废高效回采为核心的工艺技术体系，同时分析了非爆机械化连续开采技术在降低扰动、提升本质安全水平方面的应用潜力。研究旨在为我国金属矿深部开采由传统模式向智能化、连续化技术体系转型提供理论依据与技术路径，助力形成金属矿产资源开发新质生产力。
