Exploring multiple electrical layers overlying coal seams using the transient electromagnetic method. [PDF]
PLoS One, 2022 The transient electromagnetic method (TEM) is widely applied in coal hydrogeological exploration owing to its sensitivity to low-resistivity bodies. However, when a coal seam is buried deep, particularly if there are multiple electrical layers in the ...
