The resolution ability of the transient electromagnetic method (TEM) for double-layer water-
filled goaf is affected by the low resistance shielding effect of the overlying strata. Currently …

To address safety problems caused by goaf and water accumulation in open-pit mines, the
shallow three-dimensional seismic method and transient electromagnetic method were …

Underground mining in Karst Plateau landform area may cause the loss of support for the
upper rock stratum, resulting in rock collapse and large-scale subsidence of the ground …

Existing goaves (eg, shafts and roadways) in mines represent important hidden dangers
during the production of underlying coal seams. In this view, the accurate identification …

Electromagnetic (EM) surveys play a significant role in mineral exploration. However, the EM
method often faces limitations when investigating minerals in areas covered by rivers, lakes …

As already exemplified by the highly successful first volume of this Special Issue, both the
