Thin ore vein mining faces challenges such as small ore body thickness, poor stability, and high recovery losses. Backfill mining method demonstrates significant advantages in ensuring mine safety and efficient resource utilization. However, traditional methods often suffer from uneven backfilling, high costs, and insufficient recovery efficiency under thin ore vein conditions. By optimizing backfill material selection, process parameter control, and spatial layout, the stability of ore body exposure can be effectively enhanced, dilution rates and loss rates reduced, and operational continuity improved. Practical results show that rationally designed backfill systems not only improve mine safety but also achieve simultaneous enhancement of economic benefits and resource utilization efficiency.
