Abstract
The principles of determining the service life of elements of loading and delivery machines (PDM), more fully taking into account their operating conditions, have been proposed. Emphasis is put not on formation of an array of statistical data on reliability, but on analysis of loading of elements under specific operating conditions. As experience of PM operation shows, in recommendations of manufacturers on maintenance and repair (M&R) of machines, operating conditions are taken into account insufficiently. One of the indicators, evaluating efficiency of use of mining equipment is its resource. Resource characteristics of elements of machinery determine parameters of O&R system. On a choice of technique of definition of these characteristics directly depends reliability of machinery. Application of the proposed principles will allow to adjust parameters of maintenance and repair system on the basis of processing of a small number of statistical data.
