| [摘 要] 20 世纪50 年代以来,激发极化法已逐渐被普遍的应用于地质矿产普查、工程地质、水文
地质、灾害地质、深部油气等方面勘测,获得了理想的效果。但之前鉴于设备性能以及供电功率等方面
的限制,激发极化法的有效探测深度几乎一直停留在500m 之上,对500m 以下的地质体激电响应难以
准确摄取。本文所讨论的激电测深单极-偶极工作装置拟地震观测系统测深技术以其探测深度大、测深
效果好、工作方便效率高等优点正好在一定程度上满足现阶段的地质找矿需求。文章结合某Pb、Zn、Ag
多金属矿区实际应用重点对该测深技术野外工作方法与特点进行讨论,同时结合地质认识对应用效果
进行了分析与总结。 |

| Abstract:Since the 1950s, the induced polarization (IP) method has been widely used in geological surveys, engineering geology, hydrogeology, hazard geology and deep oil and gas exploration, and has achieved ideal effects. However, due to the limitation of equipment performance and power supply, the effective detection depth of the IP method seems to stay at 500 m, and electric response of geological bodies below 500 m can not be accurately obtained. This paper discusses the shock electrical sounding unipolar-dipole work device- the quasi-seismic observation system echosounding technology,which is characterized by large detecting depth, good sounding effect and high efficiency. These advantages just meet the need of the current geological
prospecting. Taking a Pb-Zn-Ag-polymetallic ore district as an example, this paper studies the field work method of this sounding technique and its
characteristics, and makes an analysis and summary of its application results in combination with geological understanding. |
