Abstract：The processing area of a large 10-million-ton-per-year granite aggregate production line is characterized by complex terrain with intensive karst caves,steep slopes,and water systems,which makes it difficult for centralized plant planning and layout.Additionally,the land transportation costs are high and pollution is severe.After analyzing the topographic features of this project,a distributed modular planning and layout solution is proposed through comparative evaluation.A primary crushing area is set up near the mining site,while deep processing and shipping wharf area are established alongside the river.A"three-stage,one closed-circuit"crushing process(primary,secondary,and tertiary crushing with closed-circuit screening)is adopted,and a dual-channel water transport network is constructed.By implementing a low-carbon logistics system featuring"long-distance belt conveying corridor+wharf shipping,"and utilizing advanced energy-saving and environmentally friendly equipment,the comprehensive logistics cost of the production line is reduced by 52%,with annual CO₂emissions cut by 38 000 tons.This approach provides a model breakthrough for the planning and layout of large aggregate production lines in similar mountainous and riverside regions(such as the Yangtze River Economic Belt and the Pearl River Delta).
