Abstract: Zhongjiu Iron Mine is a newly established mine. In order to improve production efficien⁃ cy，optimize workforce structure，and respond to the requirements of smart mine construction，to ad⁃ dressed issues such as efficiency bottlenecks，production fluctuations，and safety risks caused by tradition⁃ al ore processing procedures that rely on manual operations，based on an industrial Internet platform，a full-process automated control system and simultaneously constructed a smart command center was built. Through redundant PLC controls，high-precision intelligent instrument monitoring，and intelligent control strategies，the system achieves centralized monitoring and remote operation of the entire process，includ⁃ ing crushing and screening，grinding and classification，and magnetic separation and dewatering. It is ex⁃ pected that this solution can increase Zhongjiu Iron Mine′s processing capacity by 8%~12%，boost the an⁃ nual concentrate output by 62 000 tons，reduce labor costs by 60%，raise the concentrate grade pass rate to 98%，and decrease accident rates by 70%. This effectively enhances production efficiency，reduces op⁃ erating costs，and lays the technical foundation for less labor-intensive or even fully unmanned produc⁃ tion，while also providing a reusable technical model for similar newly established mines.
