| Abstract: | By analyzing the expression oftransient electromagnetic voltage,we can see Transient Electromagnetic Method(TEM) is more sensitive to resistivity variations than conventional DC resistivity measurement.Through researches on TEM exploration cases and geological condition of coalfield in Northern China,main tasks of TEM exploration and typical anomalous responses of these targets are summarized.Better applications in coalfield hydro-geological exploration can be expected if appropriate instrument and configuration are applied. |
