| 摘 要： | 介绍了瞬变电磁法探测采空区的基本原理.对煤矿采空区傲了正演模型,得出的异常响应对实际的资料解释有很大的指导意义.根据采空区的地球物理特征,通过分析多道电压感应剖面图和视电阻率拟断面图,可以准确的探测出采空区的位置.以山西灵石采空区为例介绍了瞬变电磁技术在煤矿采空区的应用及取得良好的效果.

| Abstract: | This paper introduces the basic principle of the transient electromagnetic method in detecting gobs.The forward model of the mine gobs is made and the obtained abnormal response is very meaningful to the data interpretation.According to the geophysical characteristics in gob areas,the multi-channel voltage sensing section and the apparent resistivity section are analyzed to detect the position of the gobs.In this paper,taking the Lingshi gobs in Shanxi as an example,the application of the transient electrom... |
