Based on typical coal mine geological models, the forward modelling and inversion modelling have been performed, respectively. To this end, this paper proposes a new electromagnetic radiation solution based on the forward and inversion theory to detect geological anomalies in the coal seam.

A challenging task using the active source electromagnetic survey technique is to detect geological anomalies, such as disaster water sources and geological structures. Hence, it is possible to use the electromagnetic radiation to predict geological disasters in coal mines. Before the rock mass explosion, electromagnetic energy will radiate outward during the deformation and rupture of the coal rocks.
