伪随机信号电法仪在河北某老矿山的应用
|
摘要
老矿山等地区存在较强的电磁干扰,这使得传统的激电仪器无法取得稳定可靠的数据。伪随机信号电法仪是基于"系统辨识"建立的一种全新的主动源电法勘查仪器,具有很强的抗干扰能力,解决了激发极化法在老矿山应用的难题。采用Abollo IP伪随机信号激电仪在河北省某老矿山开展激电测深工作,克服了强电磁干扰,取得了较好的效果,印证了伪随机信号电法仪的优越性。
Induced polarization method is one of the most important geophysical methods for mineral exploration. There is strong electromagnetic interference in old mines,and traditional IP instruments are incapable of obtaining stable and reliable data. Pseudo-random signal electrical prospecting instrument is based on " system identification". It is a new electrical prospecting instrument with strong anti-interference capability and could be applied in old mines. Based on a case study of an old mine in Hebei Province,the superiority of pseudo-random signal electrical apparatus is further expounded.
