Images of High Density Resistivity Method in Leakage Detecting of the Watertight Screen at Gushan Open-pit Mine

摘要

High density resistivity method is convenient to be used for explaining the prospected images with efficient information. In the paper, this method was used to detect the quality of watertight screen in the north slope of Gushan open-pit mine. By through inversion, analysis, explanation and speculation, the obtained results showed that the watertight screen was effective in anti-seepage, which provided technical support for the safety of slope extension at Gushan open-pit mine.
