Addressing issues such as low production capacity,high labor intensity,and frequent ground pressure manifestations in the chamber-based dry filling mining method at Jiapigou Gold Mine,this study conducted experimental research on the lightweight energy-absorbing paste filling mining method.Given the characteristics of the deep steeply inclined thin ore bodies and mining technical conditions at Jiapigou Gold Mine,the original chamber for material extraction within the stope was eliminated,simplifying the extraction process and reducing the operation cycle time.The lightweight energy-absorbing paste possesses sufficient strength to effectively support the hanging wall and footwall of the stope,ensuring stope stability and enhancing operational safety.Field application results indicate that using this method,average stope production capacity reached 20.66 t/d,an increase of 47.25 %.The mining loss rate decreased from 12 % to 3.5 %,and the ore dilution rate dropped from 8.6 % to 4.2 %.The results are promising and provide a valuable reference for similar mines.
