Failure risks of mine excavators in ranking control levels

Abstract

The paper gives the analyses of various approaches to the definition of the risk concept. The theory of catastrophes is determined to use the term “risk” in order to describe accidents and natural disasters, the theory of reliability interprets this concept as the probability of failure. It is established that there is a variety of factors that are the cause of of mining excavators failures as complex technical systems. The authors propose to establish causal relationships between the occurrence of career excavator failures, for example, using the method of event trees (failure trees) or Ishikawa diagrams.
