The article gives numerical estimates of a wireless warning system model and individual call of personnel in mines using a low-frequency electromagnetic field (ULR-range) with account for low-resistivity ore reserves. The presence of such deposits is represented by the main problem of the implementation of TTE (Through-the-Earth) communication due to the large size and strong shielding properties, which are also evaluated. The article shows numerical estimates for two long dipole antenna configuration models (symmetric and asymmetric). The comparison provides an assessment of the benefits of different antenna installation options to neutralize the shielding properties of the deposits.
