Abstract: Driven by the new generation of information technology，intelligent mine construction has be‐ come the core path of mining transformation and upgrading. Taking the construction practice of six dimensional mine of Sinosteel Mining Development Co.，Ltd. as an example，the key role of intelligent operation in the high-quality development of mines is systematically expounded. Through the integration of technology clusters such as the Internet of Things，big data，and artificial intelligence，a full life cycle management and control mechanism covering resource exploration，development，and ecological restoration is constructed to form a modern mining development paradigm of“safety-based，ecological priority，intelligence-driven，and value symbiosis”. The research puts forward that the intelligent operation is promoted in three stages: from point auto‐ mation to surface intelligence，and the whole mine intelligent management is finally realized. At present，the second stage of construction，such as digitization of geological survey and mining information，centralized con‐ trol of production，and intelligent early warning of safety，has been completed，which has significantly im‐ proved production efficiency and safety level. The key technologies include three-dimensional geological mod‐ eling，intelligent production center，environmental safety early warning network and big data decision-mak‐ ing platform，forming a three-tier architecture，four-dimensional system integration intelligent mine system. In the future，it will further promote the integration and application of cutting-edge technologies such as artifi‐ cial intelligence，Internet of Things and big data in metallurgical mines，focus on improving data standardiza‐ tion，intelligent mining control and real-time response mechanism，promote the intelligent ecological evolu‐ tion of mines to "self-perception-self-decision-self-execution"，and provide replicable technical paths andmanagement experience for the industry.
