Abstract: Driven by the national "Smart Mine" initiative and the implementation of the 15th Five-Year Plan,paste backfill technology has emerged as a preferred solution for high-quality development and the "Dual Carbon" goals in modern mining.However,as a complex non-linear system,paste backfilling demands extreme process stability and operational efficien cy.This study systematically reviews the evolution and key technical breakthroughs of intelligent backfilling across three core stages:tailings thickening,homogeneous mixing,and pipeline transport.Research indicates that intelligent backfill technology is evolving from basic mechanization and localized automation toward an AI-driven "perception-decision-execution" closed-loop system.Specifically,the thickening stage has achieved collaborative control based on deep-cone compression and "feedforward feedback" mechanisms;the mixing stage employs real-time rheological monitoring for adaptive speed control;and the transport stage has established high-precision monitoring and adaptive regulation systems.At the integration level,control systems are ad vancing from DCS-based integration toward AI-enhanced "one-key backfilling" and digital-twin-driven autonomous optimiza tion.Looking toward the 15th Five-Year Plan period and beyond,full-process collaborative operation based on digital twin plat forms will emerge as the ultimate form of this technology,providing critical support for the green and safe transformation of the mining industry.
