| 摘 要： | 利用瞬变电磁法勘察采空区,当存在较强电磁干扰时,常规测量方式无法取得准确的测量数据.在北京房山区采空区勘查中,使用了一种具有抗干扰能力强的"8"字型测量方式,取得了较好的效果.通过剖面勘查以及相应的时间域电阻率成像资料处理法,获得了较高分辨率的电阻率剖面,推断出了采空区的空间分布特征,为在强干扰区勘查采空区提供了一种新的技术方法,也为治理和防止地面塌陷的进一步发生提供了科学依据.

| Abstract: | The transient electromagnetic method is an effective method for detecting the distribution extent and characteristics of the mined-out area.Nevertheless,the measured data cannot be obtained accurately by common measurement mode of the transient electromagnetic method where there exists high electromagnetic interference.This paper introduces a 8-shaped grapheme measurement mode with strong anti-interference capability,with which a better mined-out area prospecting result was obtained in Fangshan District of ... |
