世界有色金属2023年8月下56采矿工程Miningengineering井下急倾斜铅锌薄矿脉高效开采方法探讨贺森泉（江西铜业集团银山矿业有限责任公司，江西德兴334200）摘要：银山井下急倾斜铅锌薄矿脉历经60多年的开采，浅部铅锌矿石已基本开采完，现逐渐向深部转移。现用的传统浅孔留矿法有局限性，作业环境差、招工难的问题日益凸显，急需寻求安全高效的采矿方法来替代传统的浅孔留矿法。结合矿山生产现状、矿体开采条件、提高井下机械化作业水平和用机械设备完全替代人工进行采矿作业的要求，初步选择机械化上向分层留矿法、机械化上向水平分层充填采矿法进行采矿，采出的矿石经溜破系统破碎后，再经抛废富集系统，获得高品位矿石，以达到高效开采急倾斜薄矿脉的目标。经比较分析，最终选取具有明显优势的机械化上向分层留矿法开采银山深部急倾斜铅锌薄矿脉。关键词：深部转移；招工难；安全高效；抛废富集；急倾斜薄矿脉中图分类号：TD853.251文献标识码：A文章编号：1002-5065（2023）16-0056-3Discussiononefficientminingmethodofsteeplyinclinedthinlead-zincveinundergroundHESen-quan(JiangxiCopperGroupYinshanMiningCo.,Ltd,Dexing334200,China)Abstract:Aftermorethan60yearsofmining,theshallowlead-zincorehasbeenbasicallymined,andnowitisgraduallytransferredtothedeeppart.Theexistingtraditionalshallowholeretentionmethodhaslimitations,pooroperatingenvironmentanddifficultyinrecruitingworkersareincreasinglyprominent,anditisurgenttofindsafeandefficientminingmethodstoreplacethetraditionalshallowholeretentionmethod.Combinedwiththecurrentsituationofmineproduction,orebodyminingconditions,improvingthelevelofundergroundmechanizedoperationandcompletelyreplacingmanualminingoperationswithmechanicalequipment,themechanizedupwardlayeredoreretentionmethodandmechanizedupwardhorizontallayeredfillingminingmethodareinitiallyselectedformining,theproducedoreisbrokenthroughthebreakingsystem,andthenthroughthrowawaythewastestonetoleavetheoresystemtoobtainhighgradeore,soastoachievethegoalofefficientminingofsharplyinclinedthinveins.Aftercomparativeanalysis,themechanizedupwardlayeredoreretentionmethodwithobviousadvantageswasfinallyselectedtominethedeepsteeplyinclinedlead-zincthinvein...
