| 摘 要： | 在粤东北某矿区进行时间域激发极化法工作时,人文干扰引起假异常。针对这种情况,通过分析地下通信光缆和地下金属供水网的平面和剖面异常特征,研究了人文干扰对时间域激发极化法观测结果的影响。经过与已知矿体异常特征的比较,区分出矿异常和干扰异常。

| Abstract: | During the time-domain IP work conducted in a certain ore district of northeast Guangdong Province,human disturbance resulted in the formation of pseudo-anomalies.Aimed at solving this problem,the author studied the influence of human disturbance on time domain IP observation result through analyzing plane and profile anomaly characteristics of underground communication optical cable and underground metallic water-supply network.Based on a comparison with the anomaly characteristics of the known ore body,the author distinguished ore-related anomalies from disturbance anomalies. |
