ABSTRACT

On the example of mine drifts the factors and conditions influencing formation of an electromagnetic field and propagation of electromagnetic waves in closed spaces are considered. The analysis of known publications of researches on this subject is carried out. The principles of estimating the influence of these factors from the point of view of classical models of electromagnetic wave propagation on the formation of the electromagnetic field at a given point of closed space are proposed. On the basis of which the mathematical model of formation of an electromagnetic field at the set point is offered. The zonal Fresnel type of electromagnetic field distribution is determined on the example of mine drifts. Methods for simplifying the construction of a mathematical model of the electromagnetic field are proposed, which reduces the number of analyzed factors but does not affect the overall quality of the model. The significance of the developed model from the point of view of introduction of new radio communication systems at large industrial facilities is proved.
