Interpretation Study on Low Resistivity Layer Shielding Problems of Mine Transient Electromagnetic Method
Abstract：The "isolation effect" of low resistivity layer makes late data signal-to-noise ratio decrease.The result is that the exploration depth which is expected can't be reached.Without response characteristics of the deep strata,an accurate detection of the target can't be achieved.Therefore,strata containing low resistivity layer in shallow strata can't be simply studied from the result of the transient electromagnetic detection,but should be studied with other hydrogeological data.
