| Abstract: | Theory, calculation formulas and instrument usage of natural electric field frequency-selection method are briefly discusses. Processing methods of the field survey curves and normalizing data handling based on the curves are also introduced. By actual examples in field survey, the paper shows that this method is quick, convenience and validity in surveying of karst caves and middle-shallow orebodies, and can used in appraising engineering geology, detecting subsurface faults and searching boundary of water-saturated landslides in high-resistance rock covered districts. |
