摘　　要：构造叠加晕找盲矿法是以攻深找盲为目标,在研究原生晕找盲矿理论--原生晕轴向分带基础上,提出了“原生叠加晕理论”和“构造叠加晕理论”两个新理论而开创的找盲矿新方法。构造叠加晕预测盲矿的准确性决定于预测标志与指标的正确性。本文在总结100多个热液矿床深部盲矿预测的构造叠加晕7条共性标志的基础上,将4条可定量化的重要定性预测标志提升为定量化预测指标,详细阐述了在矿区深部及外围精准预测盲矿和判别矿体剥蚀程度的17种情况不同组合的构造叠加晕预测标志与指标,并建立了预测盲矿和判别矿体剥蚀程度的构造叠加晕实用理想模型。该模型中共性预测标志与指标对典型热液矿床深部盲矿预测具有重要的指导意义,在100多个矿山应用中取得了显著的找矿效果,累计找到金金属量突破340 t,实践证明了构造叠加晕理论与预测指标—标志的正确性及准确性。The method of structural superimposed halo to find blind ore is a new method to find blind ore,which is based on the study of the theory of primary halo to find blind ore-the axial zoning of primary halo,and puts forward two new theories of‘primary superimposed halo theory’and‘structural superimposed halo theory’.The accuracy of blind ore prediction by superimposed halo of structure is determined by the correctness of prediction marks and indexes.Based on the summary of seven common signs of structural superimposed halos in the prediction of deep blind ore deposits in more than 100 hydrothermal deposits,four important quantitative qualitative prediction signs are upgraded to quantitative prediction indicators.The structural superimposed halo prediction signs and indicators of 17 different combinations of accurate prediction of blind ore and discrimination of ore body denudation degree in the deep and periphery of the mining area are described in detail,and a practical ideal model of structural superimposed halo for predicting blind ore and discriminating ore body denudation degree is established.The common prediction signs and indicators of the model have important guiding significance for the prediction of deep blind ore in typical hydrothermal deposits,and have achieved remarkable prospecting results in more than 100 mine applications.
