The main challenges in deep mining include three highs and one disturbance,deep mine hoisting,ventilation,and intelligent mining.The poor working environment and high labor intensity of underground workers result in low production efficiency and high operating costs during the deep mining of mineral deposits,which seriously affects the safety of production underground.Taking the deep mining of a gold mine in the Jiaodong Peninsula as an example,the paper analyzes it from a technical,economic,and management perspective,proposing the mechanized point-column upward horizontal layered filling mining method in the mining area.The underground working environment is effectively improved,and the production capacity of the mining area is increased by 23 %,while the mining loss rate is reduced by 20 %.The resource recovery rate and production efficiency are significantly improved.Industrial experiments show that the new mining method can meet the technical and economic index requirements,and its research results can be used to guide mine production.
