摘　　要：滇东北某铅锌矿床深部主矿体为研究对象,以矿体面积误差率、矿体面积重合率、矿体形态歪曲率等多个指标为研究参数,系统开展探采对比研究。研究结果显示:目前的勘查网度基本合理,而面积重叠率、形态歪曲率则不太理想,说明除了要严格按照现有工程网度进行布置钻探工程外,特殊地段(构造附近、小矿体赋存地段、矿体边缘部位等)的工程布置仍需适当加密;矿区常见的蚀变类型有方解石化、黄铁矿化、白云石化,这些特征均可作为重要的找矿标志。Taking the host ore body in the deep part of one lead-zinc deposit in northeastern Yunnan as the study object,taking ore body area error rate,ore body area overlap ratio,ore body morphology distortion rate and several indicators as the study parameters,the correlation studies of exploration and mining are developed.Study results show:that the exploratory grid at present is basic rationality,the area overlap ratio,ore body morphology distortion rate was not good,it means not only the exploration drilling engineering be arranged according to the current engineering net dimension strictly,but also the engineering arrangement of special locations(tectonics nearby,small orebody occurrence section,ore body marginal areas and so on)still needs to be encrypted;the common alteration types in mining area are calcilization,pyritization,dolomitization,these features can be taken as the important prospecting criteria.

关 键 词：矿体面积误差率 矿体面积重合率 矿体形态歪曲率 探采对比 铅锌矿体
