Underground coal is processed through a high-efficiency jigging refuse removal system that accurately identifies ore characteristics, enabling efficient separation of coal from raw ore and significantly improving coal quality. Among this, gangue larger than 6mm is directly backfilled underground, substantially reducing operational costs, while particles smaller than 6mm are transported to the coal preparation plant for further refinement. The remaining coal gangue and slime are scientifically blended with bio-bacterial fertilizers to transform them into organic soil that nourishes the mining area. The rich nutrient composition rapidly revitalizes the mined land, ultimately achieving the goal of lush vegetation and ecological restoration. As an integrated full-industry-chain service provider, we tailor development pathways for mining enterprises with professional expertise, comprehensive equipment, and exceptional ecological restoration capabilities, driving the mining industry toward a sustainable future.
