中国浅表矿、易采矿资源日趋枯竭,迫切需要在现有矿山开展深部找矿,研究适用于深部找矿的地球物理勘探新方法具有重要意义。本文探讨研究了井中激电地-井方式三维阵列观测方法,借助连续电性介质模型异常电位三维有限元数值模拟方法,对不同地电模型模拟的视电阻率和视极化率响应进行了模拟分析。研究结果表明:该方法有效拓展了观测空间,携带目标体信息丰富,可以有效从不同点位和层位提取曲线数据和切片数据,通过绘制相应图件从而分析目标异常的空间分布特征。本文模型分析结果可以作为异常推断解释的参考依据。 |

Easy shallow mining of mineral resources in our country are depleting, urgently need to carry out deep mineral exploration in existing mines. It is of great significance to study new geophysical exploration methods suitable for deep exploration. This article studies the ground-to-well three-dimensional array exploration method of induced polarization in the well, and uses the three-dimensional finite element numerical simulation method for abnormal potential in a continuous electrical medium model to simulate and analyze the apparent resistivity and apparent polarization response of different geoelectric models. The research results indicate that this method effectively expands the observation space, obtains rich target body information, and can conveniently extract curve data and slice data from different points and layers. By drawing corresponding graphs, the spatial distribution characteristics of target anomalies can be analyzed. The model analysis results in this article can provide reference basis for anomaly inference and interpretation. |
