Аннотация: The article discusses a number of methods that are actively used in the industrial field of mining by detonating borehole charges through a low-frequency wireless channel for transmitting activation commands from an explosive machine to a detonator located underground. The analysis of technologies used for the purposes of wireless detonation, their areas of application and methods of channel implementation is given. Consideration of market samples and patent applications of manufacturing companies showed a general trend in the use of a magnetic loop as a transmitting antenna, as well as operating frequencies in the range of 1-10 kHz, which are the main factors that do not allow their use for activating an underground charge for seismic exploration, which requires equipment for initiating seismic action of minimum deviation in time and activation of a long blast profile. Overcoming these shortcomings requires changing the concepts of building communication channels with underground charges and analysing the limit of increasing the frequency range in conditions of conducting media. © 2022 Author(s).
