摘要
"原生晕轴向分带理论"、"原生叠加晕理论"和"构造叠加晕理论"是构造叠加晕找盲矿法指导发现异常→评价异常→深部预测的三个核心理论,是提高预测准确性的关键."构造叠加晕理论"是用少而精的样品发现异常→强化弱异常→加大预测深度的一种理论,"原生晕轴向分带理论"和"原生叠加晕理论"相结合是异常评价、预测盲矿和判别矿体剥蚀程度的重要理论.构造叠加晕团队先后在17个省105个矿山邀请138次立项研究-预测应用,其中已有20个矿山提供了预测靶位验证证明,累计找到金金属量突破320 t,见矿效果非常好.实践进一步证明了三个核心理论在找盲矿中的正确性和先进性,也表明构造叠加晕找盲矿法在矿区深部及外围找盲矿是一种直接、准确、有效的方法.
Abstract
The axial zoning theory of primary halos,the theory of primary superimposed halos,and the theory of structural superimposed halos are the three fundamental theories of the method for guiding anomaly discovery,evaluation,and deep prediction through structural superimposed halos.These theories play a crucial role in improving prediction accuracy.The theory of structural superposition halo focuses on identifying anomalies with limited and precise samples,strengthening weak anomalies,and increasing prediction depth.The combination of the axial zoning theory of primary halo and the theory of primary superposition halo is essential for evaluating anomalies,predicting blind ore deposits,and discriminating ore body denudation degree.The Structural Superposition Halo team has successfully applied these theories in 138 research-prediction projects across 105 mines in 17 provinces.Among them,20 mines have provided verification targets for predictions resulting in a cumulative gold metal yield exceeding 320 t.This demonstrates excellent ore finding results while further confirm-ing the correctness and advancement of these three core theories in blind ore prospecting.It also highlights that structural superposition halo blind ore prospecting is a direct,accurate,and effective method applicable to deep mining areas.
