摘　　要：为提高铅锌矿矿区开采量,优化矿区开采安全性,研究铅锌矿矿区地质特征及矿床开采技术条件。选取某市铅锌矿矿区作为工程研究区域,通过1∶2000激电中梯测量地表、1∶1000地形地质剖面测量以及矿区深部通过钻探工程作业多种勘察方式的融合,精准分析矿区地质特征。经现场勘察得知,矿区地层岩性种类较多,且存在较强的围岩蚀变现象,工作区圈定的1条主矿体及2条辅矿体分别呈大脉状、脉状,矿区中磁铁石英岩的磁性最高,是该矿区的重点磁异常源,根据这些地质特征,获取矿床水文地质变化、矿坑涌水量变化以及矿床充水因素等条件,采用上向水平分废石充填采矿法实现该矿区的矿床开采。In order to improve the mining output of the lead-zinc mine area and optimize the mining safety of the mine area,the geological characteristics of the lead-zinc mine area and the mining technical conditions of the deposit were studied.The lead-zinc mining area of a city was selected as the engineering research area,and the geological characteristics of the mining area were accurately analyzed through the integration of 1∶2000 IP ladder surface measurement,1∶1000 topographic geological profile measurement,and drilling engineering operation in the deep part of the mining area.After on-site investigation,it was found that there were many types of strata lithology in the mining area,and there was a strong phenomenon of wall rock alteration.One main ore body and two auxiliary ore bodies delineated in the working area were in the shape of large veins and veins,respectively.The magnetic quartz rock in the mining area had the highest magnetism and was the key source of magnetic anomalies in the mining area.Based on these geological characteristics,conditions such as hydrogeological changes in the deposit,changes in the water inflow of the mine pit,and factors related to the filling of the deposit were obtained,the upward horizontal waste rock filling mining method was adopted to achieve the mining of the deposit in the mining area.
