Method of improving safe operation of mining machinery electrics by forecasting insulation resistance

The method is proposed to increase safe and efficient operation of mining machinery electrics. The use of this method in control and forecasting of electrics insulation resistance allows sufficiently accurate estimate of critical insulation resistance for a preset time period and, thus, provides failure prediction. It is proposed to solve this problem using digital technologies based on the artificial intelligence, in particular, neural networks. The implementation algorithm is based on the direct distribution neural network. The results of the insulation resistance forecasting are presented. The analysis of the obtained diagrams suggests acceptability of the results: the forecasting accuracy makes 95 %. The introduction of the proposed insulation resistance forecasting and control method will enhance electrical safety of mining equipment handling due to elimination of electric traumas of personnel in case of the current leakage protection malfunction. At the same time, this method can enhance efficiency of mining equipment through the reduced damage because of sudden outages of normally running mining machinery.
