Abstract

The article represents the results of investigation on identifying and classifying the main reasons of electrical accidents at iron-ore mines complexes. Logical models of appearing hazardous failures in the functioning system "man -mining industry-electrical complexes" and hazard actualization of electric injure in the system, as well as graphic images of hazardous states at time interval and the probabilistic model of hazard actualization of electric injure, which is derived from the logical model are given. Tabulated data on the probabilities of hazardous states and events forming an electric injure received from the data observational at mines "Krivorozhzhelezorudprom" and matrix resulting data of rank about electrical accidents reasons investigation at iron ore mines and pits, hypothesis testing results about statistically significant difference of causes electrical accidents reasons and consistency of experts’ judgments.
