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.
