介绍了三维地震及地面瞬变电磁法的原理,并对探查区情况作了概述,综合分析了2种方法的探查结果,得出了2种方法的探查结果基本一致的结论。2种方法的工程实践确定了陷落柱1个,其长轴为北北西向,短轴为北东东向。 The principle of three-dimensional seismic and terrestrial transient electromagnetic method is introduced. The situation of the exploration area is summarized. The exploration results of the two methods are comprehensively analyzed. The results of the two methods are basically the same. The engineering practices of the two methods have confirmed that there are one sinker column, the long axis is north-northwest and the short axis is northeast-east.
