摘要
介绍了使用矿井瞬变电磁法探测工作面内富水异常体的技术方法,并采用Voxler和Paraview三维可视化软件用于数据分析解释,通过合适的坐标转换和软件算法对三维散点数据进行网格化,构建三维数据体,进而选择适当的电阻率值呈现等值面图,展示相对低阻异常区的形态。同时,利用过滤器提取异常区块,深入分析异常区水力联系和分布趋势,实现水源和异常体分布情况的精确定位和展示。结合内蒙古金鸡滩矿实例,通过对比2种软件的使用流程、功能和成图效果,指出了它们的优缺点,并给出了适用条件建议。
Introduce the technical method of using transient electromagnetic method to detect waterrich anomalies in the working face of mines.It employs Voxler and Paraview 3D visualization software for data analysis and interpretation.By performing appropriate coordinate transformations and software algorithms on 3D scattered data,a 3D data volume is constructed.Subsequently,suitable resistivity values are chosen to present contour maps,displaying the morphology of relatively low-resistivity anomaly areas.Additionally,filters are applied to extract anomaly blocks,enabling in-depth analysis of the hydraulic connections and distribution trends of the anomaly areas.This facilitates precise positioning and visualization of water sources and anomaly distributions.Illustrated with a case study from Jinjitan coal mine in Inner Mongolia,compares the usage processes,functionalities,and mapping effects of the two software programs,highlighting their advantages and disadvantages,and offering recommendations for their respective applicability conditions.
