Abstract: With the inevitable trend of metal mineral resource development shifting towards deeper deposits,the integrat ed mining,beneficiation,and backfilling process has emerged as a core direction for addressing complex geological conditions at depth and achieving intensive extraction.However,conventional integrated processes based on the drill-and-blast method com monly suffer from bottlenecks such as discontinuous production stages,uncontrolled fragmentation,low separation accuracy,and poor system coordination.This paper innovatively proposes a novel integrated process utilizing non-blast mechanized mining. Centered around continuous mechanized excavation,precise fragmentation control,efficient underground beneficiation,and in situ waste backfilling,this approach establishes a closed-loop "Mining-Beneficiation-Backfilling-Mining" operational model through fundamental process innovation and modular system integration.It aims to significantly enhance mining efficiency and resource recovery rates while simultaneously reducing energy consumption and environmental risks from the source.In order to provide theoretical and technical reference for the safe,green and efficient development of deep complex deposits,this paper systematically expounds the overall architecture,key technologies and personalized solutions adapted to different geological con ditions of ore bodies.
