通过2个典型矿床的预测实例，阐述了构造叠加晕实用模式的特点和应用准则，使构造叠加晕法应用于深部盲矿找矿预测的思路更加清晰，方法便易操作，找矿效果更显著。构造叠加晕法只用于构造带内原生叠加晕轴向分带及叠加结构的研究，采样位置集中在构造带内热液叠加部位，大大减少了采样和样品加工分析的工作量，加大了预测深度，提高了盲矿预测的准确性。构造叠加晕实用模式是在构造叠加晕模式的基础上，突出了构造叠加晕法与成矿规律研究相结合开展找矿预测的新思路，具体步骤包括：研究已知矿体的赋存特点，从而确定有利的成矿空间；根据构造叠加晕实用模式和盲矿预测标志，判断有利成矿空间是否存在有盲矿。

Through prediction examples of two typical deposits，the characteristics and application guidelines of structural superimposed halo practical model are described.It proved that structural superimposed halo law applied to deep prospecting makes the ideas more clearly，much easier to operate and control，and the effect is more significant.Sructural superimposed halo method only studies the axial zoning and superimposed structure of the primary superimposed halo in structural belt，and the sampling position is concentrated in the hydrothermal superimposed parts in structural belt，so it reduces the workload，increases the predicted depth，and the key is to improve the accuracy of the blind ore prediction.The practical model of structural superimposed halo is based on the structure of superimposed halo model，and the new idea of the combination of structural superimposed halo and metallogenic regularity is highlighted.The specific steps are，firstly，study the occurrence characteristics of known ore bodies to determine the beneficial metallogenic space，and then according to the model and the blind ore prediction signs to determine whether there is a beneficial metallogenic space.
