摘　　要：基于矿井瞬变电磁法的基本理论,对综采工作面内陷落柱进行多角度方向探测,采用自然邻点方法对探测数据分别进行横向和纵向插值运算,用多个切片显示发育特征。此外,对探测数据进行三维空间插值,实现了陷落柱的三维立体显示。工程实例表明三维可视化显示能够准确判定陷落柱的发育特征及其赋含水性。Based on the coal mine transient electromagnetic theory, the collapse column in fully-mechanized mining face is detected in different directions. In addition, natural neighbor method is employed to interpolate the data in vertical and horizontal directions, and the develop- ment characters of collapse column are exhibited by different slices. Besides, a 3D display of col- lapse column has been realized by 3D spatial interpolation for detected data. The project example shows that development characters and water-bearing property of the collapse column can be ac- curately described by the 3D visualization display.
