<FFF>电法在金矿评价中的应用效果

The appraisal of “FFF” electrical method used in gold mine

概述了 <FFF >电法的基本原理和优化的工作方法 ,重点介绍在冯国华 (FGH)模型系列参数的基础上 ,创建异常特征数学模型化异常解释体系。结合金矿床的应用实例 ,在验证的矿 (化 )异常地质特征的基础上 ,探讨这一新技术异常解释方法 ,基本实现高分辨率、高吻合率 (>80 % )、抗干扰、直观的物探地质效果。实践证明 <FFF >

The basic principles and optimum working method of “FFF” electrical method are introduced.On the basis of “FGH” model series parameters,the abnormal explanatory system of abnormal feature's mathematic modelling is established.Based on the verified abnormality of mineralization,the new abnormal explanatory method is studied.The results of high resolving power,high coincidence rate(>80%),anti interfevence,audio visual physical prospecting are achieved.Experiment shows that the “FFF” electrical method has made a break through at the multiple explanatoriness of the abnormality of exciting current in physical prospecting.
