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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
