In this paper, the authors present some considerations on how to develop studies of wear (wear resistance) of mining machines for open-pit mining. First, the need to continue research aimed at adapting the A.K. Reisch’s approach was noted to clarify and improve the empirical formula to assess the wear rate of elements of mining and road machines. Secondly, it is planned to deepen research to assess the correlations between the properties of materials used in mining engineering and characteristics of their wear resistance. Thirdly, the problem of wear of elements of mining machines is considered from the standpoint of managing the phenomenon of wear. For this, the A.K. Reisch’s empirical formula can be used, and the optimization problem formulated in a general form, which is reduced to maximizing the productivity of the machine with restrictions on the rate of wear of its elements and the operating costs. Fourth, the relationship between the problem of managing the phenomenon of wear and the dynamics of mining machines is noted. Some of these researches are illustrated by examples of a qualitative nature.
