Conclusions

  1. 1.

    The author develops a deterministic-stochastic model of the reliability of mining equipment on the basis of the fundamental laws of physics and the dynamics of real processes of interaction of an article with external disturbances.

  2. 2.

    Investigation of the proposed model of reliability has revealed that in the most general case (with stochastic external disturbances and values of the internal energy of reliability), the variation of the internal energy of reliability of an article is a random nonsteady process.

To determine the expectation value of the reliability at the end of the investigated interval of time in the general case it is advantageous to use the method of least squares. For a quantitative estimate of the variations it is advisable to use a field of reliability, the value of which is proportional to the adopted confidence level, to the time interval under investigation, to the rms deviations of the internal energy of reliability, and to the intensities of the external of strengthening and destruction.
