Abstract
The article provides an analysis of low-frequency and high-frequency methods for determining the distance between mobile equipment and personnel for the purpose of preventing collisions in difficult mine conditions. The authors assessed the influence of the geology of mine workings, the earth’s surface and transport on the electromagnetic field of the VLF, LF and C range. From the analysis, a combined design solution was derived for determining the distance in surface and underground mining conditions. The proposed methods for registering the proximity of objects compensate for each other’s vulnerabilities and make it possible to implement an integrated approach to preventing collisions of mining equipment with personnel.
