the use of elecrical resistivity survey to detect subsurface channels at al-mishraq sulfar mine, north iraq

Resistivity survey at al Mishraq sulfur mine north of Iraq was very successful in detecting and delineating sulfuric water leakage's channels. Depths of the channels were ranging fro 4m to more than 160m below the ground surface and channel's widith from 20m to about 40m.
