Abstrakt: Purpose. To estimate the parameters influencing on spark safety of the electric conductors located in the underground workings. Methodology. The method of researches is based on the theory of the electrical engineering at the use of methods of high-frequency transmission of energy on an electric locomotive. Findings. The results show that characteristics of intrinsically safe zones vary depending on several factors, including the power train operation mode and the location of the conductors in the development. Safety of extraneous conductors in the area of action of hauling network can be assured by means of consideration of parameters of cable and rails laying when the hauling network is constructed. We have obtained dependences for determination of safety step of transposition for double track and single track rails, distinguishing by expression for determination of mutual induction. The results have become the basis for the construction of algorithms for the calculation of an intrinsically safe step for transposition for double track and single track rails. Originality. The values of safety step of transposition for rails with the inductive transmission of energy in the mine workings have been determined taking into account the hauling network regimes parameters. Practical value. The results allow defining the areas of safe location of extraneous conductors in the zones influenced by hauling network in the underground mine workings. [ABSTRACT FROM AUTHOR]
