直流电阻率法普遍应用于寻找矿井含水异常体,基于二维图形之上的三维电法可以直观展现立体几何模型,应用伪三维高密度电法探测,根据二维平面之间的地质构造连续性,将测量数据可以组合成近似立体的三维地质模型。选取较为精确的二极探测装置,采用WGMD-4高密度电法系统,应用圆滑约束最小二乘反演方法对探测数据进行多次循环迭代处理,综合静校正技术修饰,以三维可视化Slicer Dicer系统获取切片数据体,圈定异常低阻体大致范围,确保矿井含水异常体的精确判断。

The DC resistivity method is widely applied in the mine to find abnormal water bearing body,three-dimensional electrical method based on 2D graphics can directly show the 3D geometric model based on the application of pseudo 3D high density resistivity detection,according to the continuity of geological structure between 2D planes,the measurement data can be combined into approximate three-dimensional 3D geological model.We select the accurate diode detection device and use WGMD-4 high density electrical system,and apply smooth constrained least squares inversion method to carry out cyclic iterative processing of detection data.Through comprehensive static correction technique,the slice data body was obtained by three-dimensional visual slicer dicer system and the abnormal low resistivity range is delineated to ensure the accurate judgment of mine abnormal water bearing body.
