摘　　要：通过对铜绿山铜铁矿充填系统存在的矿山充填浓度低、给料井尾砂沉积、现有设备及仪表老旧、井下管道管阻大等问题进行分析,针对性提出了一套完整高效的自动化数字矿山充填系统升级改造方案。开展了改造成本估算和经济效益分析,得到改造成本约为1686万元,直接降低运营及胶结剂成本311.37万元/a,表明充填系统改造具有良好的经济效益。改造完成后开展了膏体充填工业试验,结果表明,改造后,铜绿山铜铁矿新膏体充填系统获得了良好的充填生产指标,充填浓度66%~69%,充填流量100~120 m^(3)/h,胶结剂单耗同比降低17.8%,显著节约了充填成本,提高了充填效率,改善了回采环境,保证了充填体质量,降低了堵管、爆管事故发生的风险,充填系统升级改造效果显著,为同类矿山提供了借鉴和参考的范例。An analysis was conducted on the issues present in the filling system at Tonglushan Cu-Fe Mine,includ-ing low filling concentration,tailings deposition in the feedwell,outdated equipment and instruments,and high pipeline resistance underground.A comprehensive and efficient automated digital mine filling system upgrade plan was proposed.The cost estimate and economic benefit analysis for the upgrade showed an estimated cost of approximately 16.86 million yuan,with a direct reduction in operating and binder costs by 3.1137 million yuan/a,indicating significant economic benefits.After the upgrade,an industrial trial of paste filling was conducted.The trial results demonstrated that the new paste filling system at Tonglushan Cu-Fe Mine achieved good filling operation indicators,with a filling concentration of 66%-69%,a filling flow rate of 100-120 m^(3)/h,and a 17.8% reduction in unit binder consumption compared to the previous system.This significantly reduced filling costs,improved filling efficiency,enhanced the mining environment,ensured the quality of the fill,and lowered the risk of pipeline blockages and ruptures.The upgrade had a remarkable effect,providing a valuable reference for similar mines.
