Abstract:

When the exploration line is longer than the prospecting section of High—density electrical survey systerm， use glide prospecting or roll prospecting method to collect data，then inverse with the amalgamation data，the result is 2D section image，contrasting it with the result of single short section prospecting，resistivity anomalies of two methods result is very consistent with chargeability anomalies in the shape and position．Long secion inverse result image call give prominence to high intensity anomaly，and SO on，it come true to contrast all anomalies grade and intensity of the exploration line with two methods．

Key words: High—density electrical prospecting, Prospecting line, Glide prospecting, Roll prospecting
