摘　　要：为解决立井井筒瞬变电磁超前探测剖面显示技术的非直观性、数据利用率低等问题,根据立井井筒空间形态的特点,设计了立井井筒瞬变电磁超前探测数据采集方法,提出运用Matlab语言和Voxler软件实现对探测成果的三维显示。文章结合某矿立井井筒超前探测应用实例,将超前探测数据进行三维处理,对异常体位置及范围进行了圈定,结果表明瞬变电磁三维显示技术在立井井筒超前探测中可以准确、直观地展现掘进前方含水低阻构造体的空间位置和延展范围,提高了瞬变电磁法超前探测的精度和显示效果。Aiming at the problems of non-intuition and low data utilization efficiency of section display technology of TEM advanced detection in vertical shaft, according to the characteristics of the shaft spatial form, the paper designs the data collection method of TEM advanced detection in shaft, and proposes using Matlab and Voxler to realize 3-D display of the detected results. Based on the application example of advanced detection in shaft of a mine, the paper makes 3-D processing on the advanced detection data, and delimits the position and scope of the abnormal body. The results show that TEM 3-D display can accurately and intuitively show the spatial location and expanded range of low resistance water-bearing structure in tunneling direction in advanced detection in vertical shaft, which has improved the accuracy and display effectiveness of TEM advanced detection.
