To address challenges such as great mining loss and dilution, high labor intensity, Iow mechanization, and inefficient mining-filling cycles in the deep orebodies of the Tonglushan Copper-Iron Mine using the point pillarupward horizontal lavered filling mining method. this paper proposes to carry out experimental study on a panel-based upward approach paste filling mining method, based on the mine's mechanized equipment and upgraded paste filling system. By leveraging recently acquired mechanized mining equipment and an optimized paste filling system at Tonglushan Copper-Irom Mine, the method eliminates stopes' point pillars, enhances ore recovery, reduces underground labor intensity. and improves stope filling efficiency. The findings provide a novel strategy for efficient mining in similar mines
