摘　　要：构造叠加晕找盲矿法已在50多个危机矿山深部找矿预测应用,矿山验证预测靶位取得找盲矿显著效果,其关键技术有四个:①第一手资料的获取:构造叠加晕特殊的采样方法;②研究和发现每次成矿形成矿体-原生晕的轴向分带;③识别不同期次成矿形成矿体-原生晕在构造空间上的叠加结构;④预测靶位的定位。文章介绍了四个关键技术的研究思路与方法。The structural superimposed halo method has been employed in search for blind ore bodies in more than 50 crisis mines, and the mine verification has provided the effectiveness of this method in predicting targets and seeking for blind ore bodies. There are four key techniques in this method：①the acquisition of the firsthand information：the specific sampling method for the structural superim-posed halo;②the study and discovery of the axial zoning of the ore body-primary halo formed by each ore-forming process;③the rec-ognition of the superimposed structures of ore body-primary halo in structural space formed by different phases of ore-forming processes;④ the locating of the prognostic target. The train of thought and methods for studying the four key techniques are also described in this paper.
