Abstract

The relevance. Recently, the diamond mining industry has included a trend of mining using the mining method. In this regard, the drive based on DC motor and AC motor has become widespread. Unplanned shutdowns of mining machinery lead to economic recession and additional costs for repairs. Unplanned break of tunneling equipment leads to industrial disasters and jeopardize the safety of person/ nel. Therefore there is an urgent problem of providing adequate level reliability of mining machinery amongst other problems of diamond industry. Early diagnostics, repair using modern technologies and constant improvement of maintenance minimize downtime and elimi/ nate sudden failure. Application of system analysis in reliability of electrical machines does nоt get necessary development. Paired com/ parisons applied in the system analysis allow analyzing the criteria reluctant to quantitative evaluation. The main aim of the research is to determine the most effective ways to solve the problem of ensuring the proper level of operational reliability of electric machines of the cutting body of the AM/75 roadheader in the diamond industry by analyzing hierarchies. Object of research is the electric drive of the cutting body of the AM/75 tunnel miner, operated under conditions of the diamond/mi/ ning complex. Methods: system analysis, hierarchy method, expert evaluation method. Results. Using the hierarchy analysis method the authors have determined the criterion which affects most of all the reliability of elec/ trical machines of cutting unit of road header AM/75. The paper introduces in hierarchy the objective tree for the problem of providing reliability for electrical machines of road header.
