【摘要】 本文介绍了高密度视电阻率成像系统的探测原理与方法,并在弓长岭铁矿一矿区进行了大范围的应用。结合成矿规律分析和已知地质钻孔柱状图,将DUK勘探数据通过计算机软件处理,绘制了地质CT图,进而形成了勘探线地质剖面图,试验结果满足了生产需要。为铁矿体空间变化与铁矿资源进行大面积高精度低成本综合性探测与评价提供了新的方法,具有重大理论意义与推广应用价值。更多还原

【Abstract】 This paper introduced the principle and method of high imaging system of density apparent resistivity, and applied it in No. 1 mining area of Gong Changling iron mine. This method integrated with law of metallogeny and known geologic drill column, dealt the DUK exploration data with computer software, plotted geologic CT drawings, then plotted geologic section plan of exploration line. The result of the experimentation satisfied the productive wants. It provide a new method to explored and appreciate space variation of iron orebody and iron mine resource with high degree of accuracy, low cost and integrated exploration, it has important theory and extend applied value.更多还原
