音频大地电磁测深数据三维可视化探讨

介绍了采用音频大地电磁测深法探测矿区深部是否具铅锌矿体分布的方法。为了更直观地分析各条剖面测深数据之间的联系和空间形态,采用Golden Software Voxler三维可视化软件对数据进行三维建模和三维网格化,通过绘制三维矢量散点图、不同高程的切片等值线图、三维曲面图对矿区测深数据进行评估和综合分析,识别和区分孤立的闭合假异常,以达到了解不同高程的电性变化规律和异常体的空间展布特征的目的,为下一步工作提供可行性参考。

The Three-dimensional Visualization Research about the Data of Audio Magnetotelluric Method

The audio magnetotelluric sounding method used to explore deep mineral was introduced in this paper. The data got from the detection was fixed to build 3D model using Golden Software Voxler. The model could help understanding the spatial distribution of the magnetic field of the Mining Area more visually. Besides, 3D vector scatter-plot, slice contour map on different elevation and 3D curved surface map had also been derived from the data to get further understand of the magnetic field of the study area. From all the above-mentioned work, isolated false anomaly of magnetic field was identified, and variation of the electric field on different elevation and the spatial distribution of false anomaly were figured out. These achievements were very important for the design of drilling.
